Sure.  People might expect the utility to complain about
what they consider to be obvious typos, rather than to
remove files they don't expect to be removed.  For example:

  rm -fr .*

safely removes all file names beginning with "." in the
working directory, without inadvertently removing file names
that do not begin with ".", or files in the parent
directory.  I can see people being used to this sort of
thing, and being annoyed greatly if we change it.

No, "rm -fr foo/" removes the directory too.

Which utilities are those?  The standard POSIX style is that
foo/ names the directory.

No, "./" is treated as ".".  Sorry.
