Not quite sure about the name - what does "sticky" mean in this context? 🤔

[stafyniaksacha]

I was thinking that sticky is a synonym of fixed, my bad ....
Hum, I'd like to have a one word option for this, but I can't find one.
What about --fixed-port, --enforce-port or --no-dynamic-port ?
I like the idea of --no prefix because it disables something

[yyx990803]

Maybe --bail?

[smhmd]

strict instead of sticky?

[yyx990803]

Ah, --strict-port sounds good and explicit.
