Maybe so.  My comment was about the inadequate doc, which does not define
or in any way explain "sub-mode", its relation to chunks of text within
a "super-mode" etc.

This stuff needs to be defined.  Can sub-modes be nested (sub-sub-mode etc.)?
Etc.  There is nothing clear about this stuff, based on the doc.  And my
comment was limited to the doc - it was not a comment about any mail thread.

I have no opinion on what should be done, other than that whatever is
intended to be added as a feature should be presented and discussed
here first (IMO).  I asked for a mini-spec of the requirements, but
have seen nothing - no reasonable description of the whole problem
the feature is intended to address.
