The overall objection is to treating ext3 as a highly mutable,
one-size-fits-all filesystem.

Maybe there is value in moving some reiser4 concepts -- a set of
metadata+algorithm plugins -- to the VFS level. I dunno.

But for ext3 specifically, it seems like bolting on extents, 48bit,
delayed allocation, and other new features weren't really suited for the
original ext2-style design. Outside of the support (and marketing,
because that's all version numbers are in the end) issues already
mentioned, I think it falls into the nebulous realm of "taste."

Rather than taking another decade to slowly fix ext2 design decisions,
why not move the process along a bit more rapidly? Release early,
release often...
