Nono...just stated the fact, that it's not completed yet and some parts
are marked as todo...That's OK!

The possible options are some ten fields, which require answers from one
or both sides. This might be OK for me (you and a few others) and
provides flexibility, however I'm not sure, if it needs this flexibility
at all...Why not define ONE secured mode, known by all parties and be
done with it? More than that, the user who should care most about the
selections really, doesn't seem to have a say...

I really would say, that there should be only a secure or unsecured
model (preferable the unsecured one not being usable) and the settings
just should be defined, like:

1.) Yes
2.) No
3.) HTTPS / XRDS)
4.) No
(5. Yes)
6.) Yes
7.) DH-SHA1/DH-SHA256
......

If there would be only ONE definition, than you'd opt for the best
available one...The optional fields would be reduced to about two or
three perhaps...

They are usable!

And who wins? I was afraid of that one...
