This is especially bad, as it might be called via a script. Could we add USE flags (probably using USE expand qt_${PN}) to qtchooser to control those symlinks and add a depend on qtchooser[qt_${PN}] to the requested qt packages?

This won't prevent people from enabling every flag in qtchooser without having the corresponding packages installed.

You could enforce deps in qtchooser via PDEPEND="qt_$PN? ( dev-qt/$PN )".

We haven't received any bug reports due to this behavior so far, and I'm worried that we may be trying to fix a use case that does not really exist in practice... Besides, both Ubuntu and Fedora seem to do the same (i.e. install all symlinks).
Closing for now. We can revisit when/if this behavior starts causing problems for other packages.
