Like Benno mentions, it is hard to say how it will look with your
description, i.e. how you plan to "cut" things.
On one hand, it sounds like you don't plan to write VFS abstractions
-- did you check Wedson's work?

i.e. it sounds like you want to replace parts of e.g. HFS with Rust
code while still going through C interfaces at some places inside HFS,
and that has downsides.
On the other hand, you mention "abstractions" around VFS concepts too,
so you may have something else in mind.

Well, apart from having to write more operations/code, as soon as
there may be writers, you have to take care of that possibility in
everything you do, no?
Worst of all, I imagine you have to test (and generally treat the
project) way more carefully, because now your users could lose real
data.
