The current codebase is somewhere on the halfway between old system 
based on multi-part messages alone and a system using labels consistently.

AFAIU this is causing problems with usability of 3.0, issues like 
"example X in guild is written for version 2.1 but it doesn't work with 
3.0" etc.

That's why I proposed reverting to old behaviour.

If people are happy with existing 3.0 behaviour, all it means is less 
work for me :)
