As much as I would enjoy backing FAA against a wall, while holding a rolled newspaper under its chin, I'm not sure of the benefit?

1. No annual / lower maintenance -

Probably not a good idea to skip entirely.
Maybe no longer tied to A&P and IA in short supply?
Allows more maintenance providers to compete and fill the shortage?

2. Cheaper insurance? -

HA HA HA.
I spilled my drink.

3. No medical? -

Currently, you need to pass a one-time 3rd class to initially get your FAA private,
Thereafter, you can go and stay basic med until you either die or are killed off.

4. Keep your existing FAA medical?

Not related to MOSAIC.
See #3 above

5. Already lost medical? - (Over minor issue?)

THAT is the remaining problem....
