In my opinion, it is "sufficient for something rather uncommon".
And in the normal usage with one build function and several package
functions, the fakeroot usage would already be less than now since the
build function does not need it.

But I find the build_pkgname idea decent, so no strong opinion on my
part. And anyway, it will be up to the people implementing it :)

That is important indeed and I never thought about it. But finally it
looks fine.
You have the main depends array that is used for the build() function,
which is checked before building the package. So there, you put all
dependencies required for building.
And then, each package is free to override it, probably for only
having a subset of the original depends array.
