Not an issue - Are ATs on common project possible?

[NullCharx]

So i've been tinkering around with ATs, and i found that a lot of my code could be on the common part if it wasn't for the necessity of access transformers. The buildgradle for common DOES have an AT definition, but is there any constraints or things I should take into account?
I added some ATs that made the IDE behave correctly but error when running.
(Now i just realized i might have understood the "common ATs" thing wrong, given they're loader specific, but leaving it up just in case)
