They're modest, but they're there.

He doesn't need to.

We'll frequently add features in the expectation that they will be useful
to a significant part of our user base.  It's a part of the decision-making
process.

Many features will have a small number of users initialy, but that grows
over time.  otoh, OMFS's user base is small and it appears that it will
dwindle.

(And in the past Linus has set the bar *much* higher for new filesystems
than I have..)
