This needs to be fixed.

It causes a build warning, and it's just not acceptable. We've had
driver subsystems do this before, and then the warning stays around
for years and nothing gets done.

The warning is not just ugly, it ends up often hiding real problems
when people get used to seeing warnings during the build.

The whole "__deprecated" crap has been a bigger problem in itself than
it has ever actually solved.

So don't do it. Either remove bad interfaces or leave them alone. None
of this "let's annoy everybody else with our deprecation messages
whether they care about it or not".
