"Pony bigger than" implication chain

pony bigger than a universe → pony bigger than a galaxy → pony bigger than a solar system → pony bigger than a star → pony bigger than a planet → giant pony → macro

This isn't a definite no, but I'm not keen on this idea for a few reasons:

1. For the largest ponies in the chain, having all the lower tags on the images gets unwieldy.
2. While the tags have "pony" in the name, they seem to be used as catch-all tags for very large creatures. Though I could set the "pony bigger than…" tags to imply "giant pony" and not "pony", "giant pony" is clearly made for ponies. As an aside, there are some non-ponies (mostly anthro, which don't get tagged as ponies) under the tag, so that tag needs to be cleaned up.
3. Some images under the tags are hyper (upscaled body parts) but not macro (entire body upscaled).

re #1: it's consistent with how our multiple breast sizes are tagged tho. Hyper breasts means the picture also has impossible, huge, and large.

I'd rather merge [>universe, >galaxy, >solar system], as well as [>star, >planet]. Having all these tags doesn't seem useful, more like just a pissing match for macro artists.
