We can still make it accessible/searchable on the web if we don't put it 
in the commit message.

I don't agree. It's quite annoying for things like annotate/blame, for 
example, where you may have to switch to another branch while chasing 
down a defective change. I also think 100MB+ is a cheap price to pay, 
given you only pay it in disk space (cheap) and initial clone time (not 
very often, and usually still quite fast). Also, at some point you 
presumably want to deprecate the whole 2.x line, right? So at that 
point, it'd be nice to have a full 3.x line with all the history in it, 
so that you can just throw away the 2.x stuff and still have full history.

I do agree that 2.x and 3.x should probably be in separate clones.

I think things are these are planned for hgsubversion, yes. I'd probably 
want to look at implementing some support for it myself if that makes 
the conversion of the Python repositories better.

Okay, sounds like that will be easy. Would be good to enable compression 
on the SSH, though, if that's not already done.
