If you write new code from scratch using wildcard imports on PyQt5, it will just work the way it has worked in QGIS 2. The point is, that some classes have been moved between modules from PyQt4 to PyQt5 (e.g. all widgets from QtGui to QtWidgets). The migration tool 2to3 can help with this - but only if the imports are fully qualified. There are other ways to upgrade your code than 2to3, the advantage of the proposed approach is that it makes your code closer to "best practice" - but it's up to you to decide.
