This isn't solely directed towards you, but as a general comment: if you're keen to illustrate a point about code behaviour (as we often are!) then it can potentially save time and ambiguity to include commit references and line ranges. It still doesn't guarantee that the behaviour is stable (because dependencies within the linked range may change before a reader gets to it) but it can help support your message (and hopefully your argument) both at time-of-authorship and in future. (and yep, it's a tradeoff of your own time -- and response time -- against future readers' time; often tricky to handle. I think code browsers could do a lot more to make it easier)
