I really wouldn't care if the BCAPL banned jump cues. I'd be fine limiting jumps to whatever I can do with my playing cue. Out of 100 or more games of 8-ball I played at the BCAPL, I believe I only used my jump cue once. So maybe I'm in the minority, but I wouldn't really miss them if they banned jump cues entirely. What I do find to be annoying about this ban is that I would have to buy more equipment now if I want to play in BCAPL events.
I was pretty happy having to only maintain one leather tip, on my playing cue, and never having to reshape or replace the tip on my break cue. I want to keep my canvas resin tip for the other 355 days of the year when I'm not in Vegas for BCAPL, so that means buying a replacement shaft or a whole new cue. Then since I only use a 2x4 case, which has been just fine up until now, I also have to pick and choose which cues to keep in there.
So you see, it's really not as simple as, "just put on a leather tip". Plus you have people saying that certain leather treatments can make the tip "just as hard" (probably an exaggeration) as phenolic. So after all this, their stupid cue balls are probably going to get "damaged" anyway.
All this pain in the butt for what? So that when they hold their cue balls close to their face, they can admire how "nice" they look?

No one has suggested any sort of test to prove that these cracks actually affect cue ball performance. So what's the big deal? I don't see them banning leather pocket liners which really do leave marks on the surface of object balls, which really does affect how the balls play because the marks can cause skids. Hmm.
So for me, it's not having to use different equipment that bothers me. It's the fact that the BCAPL is taking out a piece of equipment that has become part of the game, inconveniencing a ton of their members, and have really provided no good reason for it. Sorry but aesthetic damage in the form of tiny arcs on the cue ball when you examine it closely is not a good reason, IMO, if these arcs have no effect on play.
Of course, it's their right to do this, and it's our right to express our displeasure with it, and in the end, if it bothers me enough, no one is forcing me to renew my BCAPL membership.
