They built a lot of the optimizations into it, yes. The reason they don't want people creating custom optimized clients is that they might lose the checks in place to assure valid results. That is, if the quorum has 2 same incorrect results from badly optimized clients and 1 valid from a stock client it will discard the valid result, accept the bad results and render data from the project useless.
Even if many of the optimizations is built in to the latest version the apps are still of course not CPU specific so the crunching time increased with over 30% for all clients, never the less.

Anyway I don't care, as long as they don't use optimized clients I stay a way from that project.
(well there is also another reason, this person that always post there and I just can't stand ! 
)
I may not be able to afford the latest, best and fastest computers at the time but I want to use the computers
I have as sufficiently as possible and using stock clients is not it !
