I think that's a slight misrepresentation of the patchset. Of course, I
get reservations against adding new code but none of this code will
exist at all if the config option is not set; and the config option is
not selected by default. I don't want people to have to use something
they don't care about of course.
The patchset itself unblocks a range of use-cases we had issues with for
quite a while and the standalone, tiny filesystem approach has served us
well already, so this is not something new. It's not just gaining
fine-grained control, it's a whole set of new uses and we don't just do
it for the fun of doing it but because we do have actual users of this.
