The bulk update request #4171 is pending approval.
create implication species_sheet (468) -> model_sheet (43715)
change category species_sheet (468) -> meta
Reason: Found this tag and cleaned up the wiki page because it just said "please use model sheet instead" (added by a random user in 2018, no forum discussion i can find) which makes no sense since this is a specific type of model sheet.
A species sheet is a model sheet for a species, so it should imply model sheet and be a meta tag like it.
