I disagree that group 2 is not secure. If it was _really_ not secure it
would be a candidate for an urgent MUST NOT.

If we want users not to use bad options

That is outside the scope of this document.

This text "On the other hand, comments and recommendations from this document are also 
expected to be useful for such users." and the document says that  the groups 2 and 5 are 
allowed  "SHOULD NOT, not MUST NOT".  All of these seem to tell users that these groups 
are allowed to use.

that's not how I interpret that. I interpret that as "avoid when
possible, there if really needed".
