I don't see any problem with this change per-se, but this rationale
really doesn't explain anything in the end to the reader. How does just
having x/y-*.c files rather than x-y-*.c allow for more fuzzers to be
added? We could also add new fuzzers to the top-level now, why does this
change help us to do so.

I suspect the unstated reason is just "adding a lot more would make the
top-level cluttered", or perhaps some design reason you hinted at in
https://lore.kernel.org/git/2405897f-a774-e0d3-99bb-2185dcbb5432@xxxxxxxxxxxxx/
(but I haven't taken the time to fully understand).

So, I'm fine with this v3 as-is, but also wouldn't mind a v4 with an
updated commit message to address the above confusion.

Speaking of clutter, a much better change here IMO would be to create a
/oss-fuzz/.gitignore file, and then move these there. For prior art see:

	git ls-files '**/.gitignore'

Even better (but I'm not sure how this is all used in the end), can we
perhaps build those in a .gitignore'd oss-fuzz/.build/.

But maybe not, and in any case that would be a larger change to the
Makefile logic, so we can leave it for now, but I do think it makes
sense to create a oss-fuzz/.gitignore in a v4.
