Yes, this makes a lot of sense.
Perhaps the option should be global-local? That means that ":set" will
work as it does now, changing the value for all buffers, except for
buffers where ":setlocal" was used to specify a different value.
Although the change is straightforward, it would still be nice to have a
test for this. Thus edit a file, check that undolevels works (try two
values), split the window to edit another file, verify that setting
undolevels here doesn't change what happens in the other buffer.
Something like that.

Bypasses are devices that allow some people to dash from point A to
point B very fast while other people dash from point B to point A very
fast. People living at point C, being a point directly in between, are
often given to wonder what's so great about point A that so many people
from point B are so keen to get there and what's so great about point B
that so many people from point A are so keen to get there. They often
wish that people would just once and for all work out where the hell
they wanted to be.
