Appreciate the feedback. #2 is actually a pretty interesting one - while clearly a change in the API’s output, we were careful to make it so that maps without API keys actually still work (though they do get a heavy visual indication that they need to get an API key).

That being said, when we are talking about such large timeframes, is it fair to portray that as “regular” breaking changes?

Yes, within the context of the type of sites I was discussing. You already indicated that you know that they are not actively maintained. Knowing that, it doesn't really matter if a breakage happens every year, 3 years, 5 years. There's no point at which it becomes "OK", if you believe in the long time preservation of content.

I'm not picking on maps specifically. It's a compounding effect of many individual parts slowly breaking. I would even agree that you did a reasonable job of maintaining backwards compatibility, but that doesn't matter...broken is broken. Content gone is content gone.
