Thank you Baptiste and Gordon! I'll work something up for a comparison in jars 
and go from there.

Well, as Maven delegates some important parts like compilation to plugins or 
even external tools like javac, any risk of being different is quite low.

And put differently, as what you ask is actually controlled by the 
maven-ear-plugin, maven-jar-plugin, etc. and not by maven core (granted you 
locked plugin versions as one should do, sure), the risk is very low that 
there's anything different (without upgrading one of those plugin which may new 
behaviour and/or bug.

We migrated from m2 to m3 some time ago a quite big numbers of projects (I'd 
say more 30+ if talking about multimodule build, and even tens or hundreds if 
you speak of projects/modules), and we didn't encounter importantly noticeable 
differences.

Cheers
