While I agree with all the pros of SSH, the only issue for me is that you're spawning a remote shell which if not properly maintained / configure _could_ be a security risk, not because of ssh / key based authentication which are both great - but because you're one layer closer to the underlying OS - again which is fine if it's configured and secured properly but from what I've seen it's becoming more and more prevent for people to deploy servers / instances without truly understanding platform operations to a level where they choose a sensible OS distribution, keep SELinux enabled, run services in cgroups, automate patching etc... etc... and I think that's fine from the devaluing of operational experience and the whole replace one (modern) ops engineer with 5 devs mentality without considering that it may be more efficient to hire people and create roles based on their skill set and passion where they'll thrive best.
