I was just reading some comments about the 10.10.4 update released today, and someone confirmed that Apple has opened up TRIM to be enabled on any 3rd party SSD.

I did some more digging and this had been seen recently in the betas of 10.10.4 and in El Capitan.

It's not officially supported by Apple and is a "use at own risk" option, but it's there for those who rely on it.
