Points 1, 2 and 3 are OK
I abandoned the use of Multi System because it was too unstable after adding / removing a lot of ISO. (in order to have up to date versions)
Now I keep just a small amount of usb keys for the system I mainly use and install, and I use spare keys for testing.
And the UEFI generalization did not help : on every single computer I Wanted to test, I have a different version of UEFI, with different implementation of the "security" features leading to W10 being the only OS install able on some machines...
