>Closed source apps that compile fully static, these tend to be stable and Just Run in my experience... but open source apps? Good luck trying to bring these to even compile 10 years afterwards without going through an insane dance with Docker...

who cares?

when a closed source app fails the door is shut for good on self-remediation, unless you want to reverse engineer/break the law.

when an open source app fails to compile you can choose to put the time in to get the thing working. it's not a shut door, it's just a long path.
