Ten ball has always been played just like nine ball until the recent perversion in the WPA rules. Call shot makes the game overly complicated and more boring since it skews the game toward safe play.
unknownpro:
Depending on stance and background, many may agree with your opinion about the "call shot" and "skewing the game towards safety play" things. However, your first sentence is incorrect. Ten ball has always, historically, been played as a call ball/pocket game. (I don't like to say "call shot" because to me, that means pool as it's played in bars -- calling every rail, carom, ticky, etc.; *these* silly rules lead to more fights than anything.) Unfortunately, many of the sites that one would go to for "snapshot in time" rules from years past, don't maintain copies of those older rules and make them displayable to the public (e.g. BCA). I guess the impetus is to only have the most recent/updated rules available, so noone's trying to play by "old rules."
Wikipedia seems to have a good write-up of Ten ball, that makes some mention of the history of the game:

If you come from a 9-ball background, I'm sure folks will understand your feelings about call ball/pocket play. However, other than the different shaped rack (i.e. 10-ball's triangular shaped rack which is much less vulnerable / exploitable to soft-breaking than the diamond-shaped 9-ball rack), what good is playing 10-ball with 9-ball Texas Express rules? What, it's "kewl" to play with a double-digit number of balls on the table over 9-ball's single-digit number of balls? I don't get it. If you want Texas Express rules, just play 9-ball. There's nothing wrong with 9-ball; that's just part of the game now. The real abomination/perversion is the "you'll pry my 9-ball Texas Express rules from my cold/dead fingers" insertion into a call ball/pocket game like 10-ball, "because 10-ball is the kewl game to play these days."
I don't care at all for calling your shot. Between two decent players, lucking a ball rarely will make the difference. The only thing I see calling your shot do is start a fight between two hacks in the bar.
Two things:
1. You're not going to find 10-ball being played in a bar. Bar bangers looking for a fast-paced rotation game to gamble on are arguably going to play 9-ball, because of the ubiquity and familiarity of 9-ball.
2. Actually, "call shot" is a misnomer -- because "call shot" means calling every bounce, bank, carom, ticky, etc. that is made in the execution of the shot -- now
these are bar rules, and are more likely to cause a fight. E.g.: "that ball that you sent down the rail to the corner pocket -- it touched the cushion about a diamond ahead of the pocket, that was a bank shot and you didn't specify you were banking it!" Or, if you're playing 8-ball, and your ball category is stripes, you shoot at two stripes that are frozen together (e.g. 10-/13-ball), call one of them into a corner pocket (e.g. the 10-ball), and successfully pocket that ball, with the 13-ball moving a bit. But your opponent comes up to you and said "you didn't call which of those two stripes you were going to hit first, and I can't tell if you hit the 10-ball first, or the 13-ball first, nor could I tell if you caromed that 10-ball off the 13-ball, or it went clean" and says you lose your turn! Now that is a ruleset *begging* for fights to get started!
Methinks call ball/pocket (or "ball/pocket nomination") is more correct. And, I'll stick my neck out on the line, but if you ask *any* of the pros that regularly play the game (e.g. Chris Bartrum), they'll agree that call ball/pocket nomination is the way to go in 10-ball. (Chris B.?)
