I am not interested in two modes only if it is proved that they don't
conflict, I think two modes can cause problems.

I am interested to adopt different works/drafts, not similar solving same
problem within same WG, we need to work as a team and separate work. We can
make two drafts merged into one, but IMHO having many authors working on
two similar work is not good practice/process or not good adoption.

Why we adopt if they are not well solved into one draft, having two not
solved is worst than having only one, even in discussions in IETF, it is
very very difficult to discuss with authors of an adopted draft, it is
easier to discuss and change non adopted drafts. If I was  IETF WG chair I
will delay adoptions until we get authors to update their work and making
things clear to be well solved before WG adoptions.

This can create big debates and many discussions after adoption. Best way
to discuss with-saving times is between authors and WG before adoptions
especially when we have many similar solution-drafts

I think it is problem if we adopt without clear discussed-objectives of
each draft/author-team under investigation.
