Just finished a review and minor cleanup of these tags, and I'm not sure what to do.
Currently there are three -in_heat+heat images in the database. I'm satisfied with how those are tagged.
There are still about a dozen images that are tagged both though, and 10 more that are -heat+in_heat. (And a single image tagged estrus, FWIW.)
I'm tempted to alias all tags →in_heat, and retag the -in_heat+heat images to "hot" or something, but I didn't upload images like post #32795 and post #40014, and I don't know if there's a complaint to be raised in aliasing the heat tag.
Thoughts?
