Do I understand correctly that first problem could be solved by

stabilizing APIs used in various Linux projects? Because developers
don't want stabilizationt they invent workarounds like sandboxes?
Wouldn't it be easier to have stable API for some period of time?

You mean ABI and not API but your question is answered already in the comments at http://blogs.gnome.org/alexl/2013/02/01/developer-hackfest-status/

" Ideally we *do* want most app to share the system libs, but only those, not the non-core libraries of varying ABI stability and quality. This way we can work hard to make the core 100% ABI backwards"
