It could have been moved to a convertion tool.

Yes I know time is a finite resource, just think about all the time
that has to be spent to convert project/style files ! As I'm writing
this I'm converting the 11 (11!) style files that are shipped with
QGIS itself and are incompatible (since 3.0, is my take?).

Are style files versioned ? It could help to do that, moving forward.
At least QGIS could warn user/error out when trying to open a file
older than 3.0, and give the hint about using 2.18 to convert them.
