Just a random note: that blog post of mine is a bit outdated. A few
things have been changed in Qt's deprecation mechanisms in the meanwhile
(warnings have been made versioned, deprecation warnings are enabled by
default, and so on).
Anyway: there's unfortunately no solution to your issue except for
disabling deprecating warnings altogether. For the record, I did propose
to have special deprecation markers (special in the sense that you could
enable/disable them independently from the other deprecation warnings)
in Qt 5.15 for:
1) APIs that are deprecated in Qt 5 but without a replacement in Qt 5
itself (but eventually only in Qt 6), like indeed QNCM (AFAICT), so for
which having a warning is "useless" as there's nothing one can do about it;
2) APIs that exist in Qt 5.15.x only to ease the transition towards Qt
6, i.e. are only meant to be used during a port, and absolutely not for
"ordinary" development (like a lot of QStringView-related functionality
in 5.15 which has been implemented by doing view.toString().foo(), i.e.
throwing QStringView advantages out of the window).
The patches unfortunately were not merged before 5.15 was made closed
source, so I gave up. You can find them in the relation chain here.
