I don't understand why madvise isn't the most useful.

Because then THP stops being Transparent.

But given the difficulties redis and php and presumably other programs
appear to have, the whole idea of transparency is a bug not a feature,
is it not?

Not if every system that doesn't run redis is doing better because of
it ?

Surely it's better to have a design where programs that want to use a
new feature ask for it and programs that don't aren't forced to use

huge pages is not really a user/application level feature.
