Personally, I probably wouldn’t tag an ashtray by itself as a waste_basket – that seems too much like a trolltag. This may warrant its own top-level tag instead. (amenity=ashtray?)
Hey Tordanik! I don’t think the tag is too wrong. It could be better, sure, but I basically just want guidance and start a discussion so we can end up changing the wikis. That way, people can tag the ashtray combinations correctly!
For now, I’m going to tag it like I described, we can automatically change all tags with ashtray later, right?
In theory, it’s quite easy to automatically change tags once there’s a consensus to do so. The hard part is actually getting people to agree which tags should be used, of course.
And yes, I agree with your original point that it feels somewhat redundant.
