I told you guys to use a separate tree exactly to avoid wasting ressources if people don't use IMA. You guys back then promised you would not ever turn it on in distros nad just use if for research. Fact is you pressured distributions to turn it on now, and you fucked up the requirement to not have any impact if enabled bu not used. After fixing that mess it should be a lesson to not take more of this crap that no one is going to use anywya.
