Yes, please.  I agree with you that the normative component is already
taken care of by "don't be buggy", so if can be written in the
"informative" style, that would be great.

Also I suppose some discussion on debian-devel has already taken place
to make this pre-dependency possible without worrying about policy
§3.5?  If not, I'd be interested in either an explicit exception or
the perfunctory discussion on -devel, whichever is easier.
