Yes, in a team working remotely it is often useful to link to a specific chunk of code during a (voice or chat) conversation. Typically you're talking about the current code in a branch, and it is useful for the person clicking the link to know that we are in fact talking about HEAD and not a specific commit. This is the equivalent of calling someone to your desk and pointing at the screen. It is fine if those links stop working a few hours later.
