The folks who want this have maintained an out-of-tree patch using
strings.  They've maintained it for the better part of a decade.  I
don't know how widely this shipped in the Android ecosystem, but I
suspect we're talking about billions of devices.  Right?

This is a feature that, if accepted into mainline, will get enabled and
used on billions of devices.  If we dumb this down to integers, it's not
100% clear that it _will_ get used.

That's a pretty strong argument in my book, even if the contributors
have difficulty articulating exactly why they want strings.
