I don't know if it's the best approach.
I would tend to prefer an approach where a configure option can be given
to have the libexec stuff installed there:
./configure --prefix=/usr/local
installs in /usr/local/{bin,sbin}
./configure --prefix=/usr/local --use-libexec
installs in /usr/local/{bin,sbin} + /usr/local/libexec
That's just a *quick idea* to illustrate that the solution could be
between keeping libexec like today and getting completely rid of it
like you suggest.
Whatever we decide, it will be when Charles is back from vacation
anyways, I don't want him to come back and be surprised with that
change without him even being involved in the discussion ;-)

You should keep "Linux" out of the equation, we want to find solutions
that accomodate all systems we run on (FreeBSD, NetBSD, Dragonfly, OSX
and Linux) and we don't want to accomodate just the most popular :-)
A generic solution like the "--with-libexec" would for example make the
situation better for your system and others without mailwrappers, while
still providing the libexec/ indirection for systems that use them.
