If yes, perhaps there are relatively easy ways to address this.

I.e. configure the custom binding to also work on lock screen. Karabiner supports this I think.

Alternatively, rebind caps lock with a custom binding and not os settings (i.e. don’t rebind keys in both a custom tool and the OS). Then, if custom bindings don’t work on lock screen, you get the default, working keyboard on lock screen.
