Comment (by dgoulet):

 Oh fine idea!

 Quick question here. Can a relay have N rsa keys (for N > 1) for 1 ed25519
 key and still keep it's uptime/weight?

 I'm asking here because we currently block by RSA fingerprint but what if
 I can rotate that everyday (or when blocked) but still keep my consensus
 weight because my ed25519 is still recognized by dirauths?
