About USE flags, it's completely different idea from IFC or ICC flags.
Just couple flags only (could be more, for example if some devs and some 
users want to support alternative java machines, not system default for 
their ebuilds) which tell that you want to for something to be compiled 
with alternative set of compiler and compiler flags, differ from system 
default. It just flags that provide extra-functionality. OK, probably it 
can be done in different way, here I agree. But currently it looks with 
/etc/portage/package.use very simple and comfortable and coming into 
gentoo really very smoothly.

BTW, I'm not asking to make something for me.
I'm just telling that there is place, where extra functionality can be 
added into gentoo. And I can work for that. Anyway I do it already :)

And I just want to discuss the possible ways of implementing it.
And for sure currently there is no normal and comfortable ways to have 
it. Probably as usually my explanations not so good :)
