What about using it for locating missed approach holding points (a-la
NDB or DME substitution)? Since the database is out of date, you
can't use it for approaches, even non-GPS.

Yes.. you can.

Indeed. The usual verbiage is

"IFR enroute and terminal navigation is prohibited unless the pilot
verifies the currency of the data base or verifies each selected
waypoint for accuracy by reference to current approved data."

NDB and DME substitution on non-GPS missed approaches is a terminal
operation.
