In my experience, software support is pretty wide. I do have an RSA key in case the ed25519 isn't accepted but I think it's been a year since I've had to use it. The much nicer part about Ed25519 is that you can realistically type it out over a serial console or over a monitor-keyboard without access to copy-paste directly. They're small and fast and convenient. In addition to that, the cryptography behind Ed25519 is much simpler to implement than RSA without causing massive side channel leaks, so that is one less thing to worry about. In terms of Anti-QC Resistance, I wouldn't worry about it until we complete the current qc-resistant crypto competition, which should give us a nice set of primitives to use.
