Thank you for your supporting  words.

and gnustep-back too :) of course

That is a direction I want to discuss with other core members. Maybe 
it is possible with some clever use of macros and perahps defining a 
perimeter in methods, or splitting classes and libraries. But a hard 
migration for me is unacceptable.

This would of course pose a limit: the use of libobjc2 features inside 
this "core", e.g. thorugh an upgrade like the scripts David metnioned. 
ALso it would be an additional burden buecause two setups should be 
tested (but in a certain sense, this is already done, but it is not 
diverging).

I think this "migration" was put into air without thinking too much, 
but just by the desire of it.

Just my 2c here.
