Should pick up the vsql workflow changes on your next commit.

hm, that is interesting ... why do we have both .ssl and .encrypted fields 🤔 .
That seems like an invitation for subtle bugs, when they are not both set, unless it also allows for some kind of encryption, != ssl 🤔 .

[spytheman]

Good work.

[JalonSolov]

I wondered about having both ssl and encrypted... shouldn't they mean the same thing? At any rate, I didn't spend enough time examining the code or the specs to see if there was a valid reason I was missing.

[spytheman]

I think the gcc job has stuck.
I am merging it as it is.

[medvednikov]

should definitely only have encrypted

[JalonSolov]

Right now, it has all 3 of ssh, starttls, and encrypted. Seems like triple redundancy.
