Totally agree with you. If one has a concern due to hitting things, a
thin "sacrificial" strip can be added to the bottom of the keel. Can be
a strip of white oak or metal of choice and simply screwed into the
bottom of the keel with a suitable bedding compound. Or a couple layers
of 4" glass tape, just like on the bow or chines.
Recently a builder was chided on the WB forum for using epoxy and screws
installed from inside on the rub rails of his build. "How are you going
to replace them?" was the outcry.
The reaponse was "I don't intend to replace them or ram into any docks.
But I also plan to use fenders."
Anyway I see no reason to glass a keel and face the challenge of running
the glass around a 90 degree angle. Either way I doubt it will likely
have to be replaced any sooner than the bottom would.

16. In the end I glassed the whole bottom of the boat, added the keel,
then glassed over the keel. That way I should be able just to replace
the keel at some stage in the future if it becomes damaged.

ready to clip the copper wires down on the joints. I will wet the
joints, add epoxy fillets, fair, and then double glass with 4 inch wide
tape. I want to add the keel to the bottom straight onto the wood with
screws from the inside and epoxy it to the hull. I am then thinking
about putting a very generous fillet between the hull and keel and then
glassing over the bottom hull with a 50 inch wide by 16 feet cloth. The
plans seem to have you glass the bottom first and then add the keel.
Others have caulked in the keel over the glass. I don't know if there is
another permutation of epoxying the keel onto the glass? Anything wrong
with my approach of adding the keel first and then glassing? Does the
keel need a sharp edge to the water on the sides of it? Also need to add
the skeg to the keel at the back.
