Many. Many many.
1: Many of my modules run their unit tests if invoked as the main
programme.
2: Several modules are their own utility programme. I've got a heap of
these - anything that provides useful access to something can often be
usefully used from the command line.
A quick grep from my bin directory shows stuff like this:
[~/hg/css/bin(hg:default)]fleet*> grep ' -m cs.' *
beyonwiz:exec python3 -m cs.app.beyonwiz ${1+"$@"}
calibre:exec py3 -m cs.app.calibre ${1+"$@"}

iphoto:exec python3 -m cs.app.osx.iphoto ${1+"$@"}
maildb:exec python3 -m cs.app.maildb ${1+"$@"}
mailfiler:exec python3 -m cs.app.mailfiler ${1+"$@"}
mklinks:exec python -m cs.app.mklinks ${1+"$@"}

Consider: if you write a package, would it have a __main__.py?
Well, if the answer is ever "yes" then the same applies to ordinary
modules, simple enough to not be worth splitting onto a package.
So, yes, for me this is really really common.
Even for my current client project, which is largely a package,
several of the individual modules within the package have their own
main programmes for testing and for various utility tasks dealing
solely with that particular subsystem. There's an overarching shell
script to set up the environment and then do various things from the
command line, and it directly invokes particular modules for some
operations that act only on one subsystem.
