IMO opinion enriched-mode actually serves two purposes: (1) editing of
(very restricted) WP-like documents in the format text/enriched (2) a
means to save the colours that appear in a buffer in a file.
The difference is subtle. A usage scenario of type (1) would be, for
example, that I'd want to keep notes with some text properties in a
file. I'd create that file for this purpose, use text-mode as a major
mode, turn on enriched-mode and then specify myself explicitely which
text properties to use with M-g. A usage scenario of type (2) would
be, that I have a buffer that got its text properties from some Elisp
function and I want to save that buffer to a file, while also saving
the text-properties -- or at least the colours. For instance, when I
save my IRC logs (from ERC), I turn on enriched-mode before that.
As (1) enriched-mode should clearly be a major mode IMO, a derivative
of text-mode. If, for instance, a user wants to keep notes in a file
in the format text/enriched, then I can't actually see the point of
having text/enriched as a minor mode that is used together with
text-mode instead of just being a major mode.
As (2) it should be a minor mode, of course. However, currently some
of enriched-mode's features that make it suitable for (1) get in the
way here. For example I can't just turn on enriched-mode in an ERC
buffer, because enriched-mode rebinds RET. As a minor mode, it should
only affect the way a buffer is saved to a file and nothing else.
So I'd suggest to make enriched-mode a major mode and create a new
additional minor mode for the purpose of (2).
There is a technical problem with making it a major mode: currently
format.el expects modes specified in `format-alist' to be minor
modes. However, fixing this would be an improvement anyways.
But maybe this all can wait until after the release. I believe that
(1) is the way it is used most of the time.
