evolve in core mercurial, feature proposal: push -T topic

[Uwe Brauer]

Hi 

Any idea or plans when evolve will be part of mercurial core?

It so happens that sometimes I have two heads on one branch because I
use two topics, I cannot push them, without either 

    1. Merge them

    2. Or add bookmarks and push them. 

That's why I think 

 hg push -T topic 

Would come in handy, of course in order that this works, everybody would
need evolve and the topic extension enabled (I presume that was similar
to the situations many years ago when bookmarks were not part of core
mercurial)

What do other think about such a feature?

Regards
