Well, you could certainly argue that it should, but the fact is that
Kconfig doesn't take dependencies into consideration when it handles
selects, E.G. nothing stops you from select'ing a package with
unforfilled deps.

Webkit is furthermore C++ code, so that part is atleast correct.

 Hans-Christian> And then make a depends on package icu instead?

No, I don't think hiding applications until you by accident manages to
enable all the required libraries is a good idea.

Applications should select their library dependencies and depend (with
a comment) on toolchain features.
