The pattern I see here is that we get into trouble when we _pretend_
that builtin aliases are real commands, and not just handy shortcuts for
the real commands.
IOW, if a user is told that "git less" is the command to look at
objects, then they will:
1. get confused when "git less" claims to be "git cat-file" or "git
show" in error messages
2. get confused when there is no "git less" manpage
3. get confused when their coworker's "git less" behaves completely
differently
OTOH, if a user is told that "git less" is an alias for the user's
preferred method for viewing objects, that the default is "git show",
and that they can customize it themselves using alias.less, then I don't
think any of the above will be surprising.
So I think it is a bad idea to use such aliases to satisfy user requests
for simple commands, even when they can obviously be implemented as such
an alias.
That being said...

I think "checkin", "ci", and "co" are well-understood as aliases (and
will be doubly so if they are presented in the documentation as such).
After all, they come from CVS, which treats them this way:
$ cvs co
cvs checkout: No CVSROOT specified! Please use the `-d' option
