fail2ban is a real pet peeve of mine because anyone security conscious enough to deploy this will have likely already mitigated any actual security risks this could help with either by using a strong password or public key authentication.
That leaves noise in the logs - which sure, it's nice to reduce, but using an alternative port can help here.
I may sound like a spoilsport - but the fact that there have been a number of security vulnerabilities (https://www.cvedetails.com/vulnerability-list/vendor_id-5567...) in this project, make it worse than security theatre, it actually increases risk whilst not at all reducing it.
