mass update too_many_arms -> extra_arms
nuke too_many_arms
Justification: too_many_arms is a rare tag that seems to be intended to be used when a large number of arms are present in the image. This requires to much of an evaluation for when the number of arms becomes "too many". I request that the too_many_arms tag is either nuked entirely, or quantified when the number of arms meets the requirement. In the event this request fails to pass, then it is also my recommendation that too_many_arms is gardened further to increase its visibility.
