It will be a dependency for the upcoming security/py3-paramiko port.

I'm guessing portmgr was added because this is another py3- port and we don't have many // flavors will fix this. The flavors solution is still in progress, but I see no harm in moving forward with this for now.

A pre-commit block on py3-* ports was added, which now has a portmgr approval bypass (after @bdrewery's recent change), thus the blocking reviewer

We imagine/assume the approval context has been communicated within the portmgr team
