In your own documentation you point to latest version of sshfs... https://github.com/osxfuse/sshfs#latest-version, so why does this repository exist, given it is also an older version that doesn't seem to be getting any updates from upstream.
Also, the website states that there is a powerpc+intel binary for version 2.5.0 of ssfsh is available for install. Is that supposed to work with Apple Silicon M1 Macs? If not can we please move on to arm+intel binary? And perhaps even use a more recent version of sshfs in the process, I see its already at version 3.7.2??
