Would be good to tell them that for CUPS 3.x use of CPDB is required.
For CUPS 2.x the direct CUPS interface can be used and CPDB also works
with CUPS 2.x (CPDB works with any CUPS).
Once CPDB support has been implemented, that can be added to the r

Good, then I currently see no blocker for requiring CPDB for CUPS 3.x support.
Distros will then become aware once they're packaging any software depending on
CPDB at latest.

Michael, Biswadeep will take care of the CPDB interface, but the
CUPS/PPD interface also needs attention, as if it is not done correctly,
it will cease to work if CUPS 3.x is used (also if the CUPS Snap or any
other containerized form of CUPS is used).
