How small are the drives you are actually using? If a drive fails, can
a new one be purchased? I guess so. The smallest I can find is 80 GB
for $16, but it would probably cost almost as much for the 5.25 adapter
to 3.5. Also, how many months would it take to build LFS on a 486? The
fastest I found was 100MHz.

That's rationale. The idea is simplification for developers, including
LFS. I think the case can also be made to remove /usr and just promote
the directories there, but that's more intrusive. Besides, it's just an
idea to discuss.

I don't foresee a lot of changes being required. They can be made as
packages are updated and the changes would probably all be simplifications.

There's no need to be nasty.
