I agree with you that most often the number of files increases more
slowly than the size of the filesystem, but there are cases where
this isn't true.
News is the one example that everybody knows.
True, but for a good news server you generally have to tune a lot of
things anyway. And any decent news server maintainer should be able to
tune a filesystem appropriately.
I think you can print a warning if your "new guidelines" aren't
followed, but I don't think you should force your new guidlines on
everybody. (well, we're talking about changing the default. But nobody
ever changes the default....)
The problem is that a default has to be best for most people. Linus
pointed out to me, probably correctly, that one of the reasons for our
lousy performance on the Mindcraft benchmark was probably related to bad
defaults for the filesystem. And there are going to be far more file
servers and web servers than news servers used by users, so it makes
sense to make the defaults be optimized for the more commoon usage
scenarios.
