2.0.53 is pretty much closed. After it hits 2.0.53, the only -r releases will 
be for major regressions and security fixes. The only reason I think killing 
of CDEPEND for 2.0.53 is okay is because nothing uses CDEPEND (I killed off 
emerge scanning it already) so there's nothing to regress.

That would be splitdebug or -splitdebug. I was suggesting stripdebug as a 
replacement for -nostrip to get rid of another no* option and so that portage 
could still be configured to give the current behaviour. As far as I can 
tell, there are three possibilities:

* Do nothing
* Split of the debug info
* Strip any debug info

Have I got that right?

There's no need to touch the profiles. /etc/make.globals defines portage 
defaults and is controlled by portage.

There's no passing back of variables at the moment except through temporary 
files. Perhaps USE and *DEPEND could be read in and *DEPEND rewritten out 
after dyn_compile() completes?
