That looks more like: "if the manufacturer issues an AD [1], you'd
probably better do it, whether you legally have to or not".

[1] in this case, installing a locking device onto L'Hotellier
connectors.

This is the subject of a BGA AD in 1993 for the ASW-20, so I don't see
where you get the "manufacturer AD" bit from, even though it does
appear in ASW-20 TN-17 on extending the service life beyond 3000
hours.

As the AD in question refers to the requirement for a locking pin in
the Hotellier, I'm a bit gobsmacked that these couplings could ever
have been used without a locking pin or shroud: there's no way you
could inspect the check hole after assembly (other than poking
something through it) on wing control circuits in the ASW-20 and other
gliders. Admittedly you can see the check hole for the elevator, but
that's the only one that is easy to check by inspection on a '20.
