Similarly, on pages like GitLab you can link to specific line(s) of code in a file...but it often is the head of that branch. The URL will resolve in the future, but its pretty common that the chunk of code has moved.
I wish it was easy to grab a URL for that specific version, with a banner at the top saying it's not the newest version of the code (something I sometimes see with documentation). I don't see why Figma couldn't do this, too.
