It would seem to me that this is a good thing. If you loose power in the
airplane, and then somehow get it to come up again, and you're still in the
air, it would be preferable to have the transponder stick to the last code.

If you're on the ground, this can be easily resolved with a club-wide
checklist item update.

My club is upgrading our collection of CNX-80's to the new GNS-480
software. We've noticed that when hooked up to a slaved xponder, the
squawk code is no longer reset to 1200 when you power down the unit.
The way we noticed this is having a few people "reminded" by the tower
that they should be squawking 1200 on VFR departures :-)

The units used to power-up squawking 1200. Now they come up
remembering the last code entered on the previous flight. This
doesn't seem very useful. Is this a deliberate design decision by
Garmin? Something imposed by the FAA? Or is it just a configuration
setting that can be changed by the user?

By-the-way, the vertical guidance on non-precision LNAV/GNAV
approaches is pretty neat. Constant descent profile, instead of dive
and drive. Less workload, easier on the engine, just all around
better in every way.
