For questions that are scoped across any and all editions of D&D we have the tag dungeons-and-dragons for that (among its uses).
Twice in three days I've noticed questions about monsters across D&D editions and tagged with dungeons-and-dragons being voted closed as “unclear” and comments asking for which edition the question is about.
- Does an Ooze (Gelatinous Cube) float?
- Has there ever been a quasi-lich in an official TSR or WoTC publication?
I'm a bit perplexed by this, because from my ancient, hoary perspective on tagging, these seem to be well-scoped, on-topic question that are correctly tagged with the “pan-edition” D&D tag. That perspective does mean that (as in some past meta discussions) my understanding of “the way things are done” is sometimes dated enough that I'm out of sync with what a large of the active community thinks is “the way things are done”, so I'm honestly wondering what's going on behind these events.
Is there something I'm missing? Is there a shift in how the community expects edition tagging to be done — and by extension, is there a change in whether we accept pan-edition D&D questions? If so, is this a change we want to enshrine via consensus discussion, or is it something that needs course-correction?
