Doesn't this open a can worms?  What do we do with several trailing
slashes?  E.g. my FreeBSD box does:

$ find /bin | sed 2q
/bin
/bin/cat
$ find /bin/ | sed 2q
/bin/                           # shall we drop this one too?
/bin/cat
$ find /bin// | sed 2q
/bin//
/bin//cat

Things get more interesting if the path is a symlink to the directory.

$ find /home
/home
$ find /home/ | sed 2q
/home/                          # <- cannot drop this one
/home/uwe

What if the output from find is intended to be used as part of some
other name?

$ find /usr/src/ -type d | while read d; do echo $d/CVS; done
/usr/src//CVS
/usr/src/lib/CVS
...

Does the double slash in the first line bothers you too?

As Christoph pointed out earlier in the thread, it's not always a good
idea for a program to try to get "helpful".

I mean, find *works*.  The names it prints are correct pathnames that
resolve to the files you expect.  Does minor eye candy really worth
the trouble?
