I've been doing some logging using filters, actually. Kind of "separation
of concerns". Methods themselves concentrate on just getting functionality
right, and the filters 'slice in' and do logging.

other things if and when I get them ready and am allowed to release them.

Anyway, that all sounds pretty nice.
