What worries me as a developer is:

* Should I promote my packages (optified) to Extras when they depend on things like python (non-optified)?
I don't feel very well about my users doing it.

Put the example python because obviously it's my first interest (and it's in Extras yet), but the same could say for Qt dependencies, (even gtkmm/hildonmm?). AFAIK these are neither optified, and perhaps never will be.

In my opinion the real problem aren't the applications itself, generally they are few MB, but the dependent libraries.
People doing testing should check more these libraries.
