QtQml 2.15 is part of libQtQuick 5.15, which you should already have if your 
system is up-to-date...

Actually, (at least some of) these warnings may even be new in Qt 5.15...

Yes, they mainly inform developers of possible (current or future) problems in 
the code.

This warning talks about changing the code to "import QtQml 2.15", not that 
the user should upgrade to that version.

But that's not possible for Plasma 5.19, as this would mean that Qt 5.15 is 
the minimum version, and Plasma 5.19 is supposed to support 5.14 as well.

"deprecated" just means that it (should) still works for now, but may break/be 
removed in future versions.

Kind Regards,
Wolfgang
