The negative aspects of the linkage arrangement have been mentioned previously. The database has in the past contained examples such as over 10 erroneously linked military profiles, which were common only by their having the same model description and could only be de-linked by deleting all but one of connected registrations and rewriting each of the other profiles in turn.
A better system may have been to include a field in the profile page to add 'live' connected registrations which would not be hard wired in data terms as is the case with the current linkage arrangement.
We already add notes through the comments system to connect airframes. This is of particular use where several successive registrations are realised and avoids having to raise further profile pages which may not be of interest at the time.
I agree with Peters suggestion and will re-edit the two profiles accordingly.
