To be honest I like that APA has removed the push-out after the break. IMHO the push-out is rarely executed properly by your average to low level players. Giving an SL1-4 the ability to do a push-out is just going to confuse them and cause them to make stupid mistakes that higher level players will be able to take a lot of advantage of.
Remember, the goal of the APA is to make pool enjoyable for recreational players and to make it accessable to new players. Things like the push-out is confusing to most new comers as they have never seen it in their recreational playing. From what I have seen the APA is doing a pretty good job in bringing in new players and allowing them to enjoy the game. As there are such a small number of SL8/9's changing the rules to help them would impact 90x as many people as it helped. To be honest, IMHO I don't think the APA is worried about losing SL8/9's due to the rules, but they are worried about not bringing in new players. IIRC it's something like 1% (possibly less) of APA players are SL9...
I just like to look at APA as a great way to get myself out to play pool every week, drink beer, and hang out with friends. I think a lot of people try to look at it as something else, and thats when they get frustrated with the rules...
Just my $0.02...
