I don't think we should.  qtquick1 may not be as dead as we'd like it to be. 
I'd rather keep the QtCore API just in case someone is keeping the old module 
working for their applications (or Linux distribution, though I can't find 
any). They may also be (ab)using QLibraryInfo::ImportsPath for some other 
purpose.
