No, I didn't see this solution before.

Sounds good, only one remark:

- What if there are two packages e.g. "tcltest" and "tcltest", where
  the lower-case package is found first. Then what happens is:
         package ifneeded tcltest script1
         package ifneeded Tcltest script2
         package ifneeded tcltest script2\npackage provide tcltest ....
  So, the lower-case "package ifneeded" for Tcltest overwrites the
  original "package ifneeded" for "tcltest", so "tcltest" can never be
  loaded any more.
  Solution: before doing the second "package ifneeded", check if
  there already is one. If so, don't overwrite the previous.
The nice thing is that this works for C packages and for Modules
as well: the script that does the "package ifneeded" determines
the casing of the Module filename, nothing changes there.
That's very nice.

I don't think that using an ensemble for this is even neccessary.
This is worth investigating further.
