No, I make a malicious hobby of giving people bad advice just for fun...nya-ha-ha-ha!

How often to you install/remove the rear wheel?

This _might_ be a minor issue with indexed shifting.

Not a problem if you can live with friction, as I imagine would be the case for Pete's Hetchins.

Huh? Where? Loctite is for threads or for press-fit assemblies.

An easier answer would be to drill and tap a hole for the adaptor claw's mounting screw. This would be easy enough on the mild steel dropouts uses on Super Courses (not so easy on the chromed, forged dropout of Pete Naiman's Hetchins.)
