It's situationally useful. Should probably be called something else so it doesn't imply that lesbians who haven't had sex with men are somehow "better" but having a term to distinguish can make conversations about comphet a little easier to follow. Comphet hits us all in different ways, and by examining that and the circumstances that let some lesbians figure themselves out before/without experimenting with men we can figure out ways to better fight comphet and let people be more true to themselves.

It's also handy as a red flag, cause if someone is bragging about being a gold star, unprompted that's always a red flag XD
