Last time I did that it refused, telling me Qt (3.3.8 with security fixes)
didn't have sufficient support. I think it needs distro patches to Qt...

I think you're right. I never noticed that before. I find it odd that a feature in KDE would require external patches to Qt, but I guess that's the kind of situation they were in at the time.

Getting hidden visibility to work with C++ was tricky, as I recall. You
certainly have to appropriately mark ancestors of classes that are being
so marked to get any real reduction in symbol count, which means Qt does
need marking.
