Exactly.

No, the issue I raised concerns only conditions of the face
definition.  All conditions should be preserved with changes
made only in the condition for the current environment.
This would allow not only to keep conditions for other environments
in the saved face, but also to customize them independently
on different environments (most frequently switched of which are
light and dark backgrounds, where such improvement will be most useful).
