I agree entirely with you, it is the most natural and reasonable way
to deal with it (and Windows doesn't come near it, in case you
wonder). But different flavours of Unix _do_ behave peculiarly on
this score: I have seen directories being converted to files and worse
because of the different options with trailing slashes.
It's a hornet's nest. It probably can be fixed, but it needs more
than a few voices in the wilderness to come up with a solution that
will satisfy common sense, convention and die-hards.
But we're certainly approaching it with some useful wisdom.
