They will all use the private copy.

The creation of a private copy is just a configuration option for sip. I would expect Linux packages to continue to do exactly the same as before as far as sip is concerned. For PyQt5 the dependency on that sip package should be removed. The choice is then to create a new package containing PyQt5's private copy and make PyQt5 dependent on that - or just to include the private copy in the PyQt5 package itself.
