The code base for the actual base lining is in bnd (for both maven plug-ins). Therefore for
the same underlying bnd version both should emit the same recommendations. Try upgrading to
version 4.3 and otherwise please create a bug for bnd.

I agree. Should we set fullReport to true in the upcoming parent?

output a warning if a package version is increased accidentally to a higher number than required
(e.g. to 1.0.2 instead of 1.0.1)
Please create a bug at bnd for that.
