I think it makes complete sense to break -next (not mainline)
and force
people to fix defects. Especially these types of
defects that are
trivial to fix.
I already sent patches a month ago for all decimal only
defective uses of GENMASK
https://lore.kernel.org/lkml/cover.1562734889.git.joe@perches.com/
A couple of which have _still_ not been picked up.
These have been applied in -next:

(and that's a rather sad indictment of lk process defects)

At least these last two do not seem to have actual uses.
