This is really getting off topic and I should really not keep this
thread alive anymore. However, I'm not sure that your test case shows that

1. It works the same when the environment variable is set using the
   techniques of the LilyPond installer, as compared to setting it
   via the control panel (it probably does).
2. The setting is seen by programs that are started by double clicking
   an icon or using drag&drop onto the icon, which is the way LilyPond
   is used by virtually all first time users.

That's correct! No other environment variables are set.
