Oh!  Hmm.  The difference seems niche i'd say.
Btw now that i look at that thanks to my configurable header
display in the console based MUA i use, you use Ed25519 first and
then RSA, forcefully breaking the incapable IETF DKIM checks and
Microsoft as a whole.  That is brave!
I follow (a bit) by re-enabling Ed!!

Ciao, and greetings from Germany!
