The reverse tag is very meta, covers several categories. I nominate it to go away.
I would agree; many of the questions tagged would be covered by the
reverse-polaritytag latest questions tagged with reverse-polarity.
The first question in the latest for
reverse is asking about a reversing light circuit on a car. How that adds any value to the question is beyond me.
The term reverse covers such a broad range that a proper definition would appear to be impossible and that being the case it adds no value (but does clutter the tags with a meaningless entry from my perspective)
