In most cases it's either or both depending the book in question.
In this case when you have a small pool of LGBTQA+ characters-it's easier to remember.
Especially one in a Bunker who aside from Batwoman, Tim Drake (now), Aqualad, Hellblazer and Todd Rice-has a ton of appearances in books.
Remember he was in a Teen Titans book not the New Guardians or Baby Doomsday.
That is a book that will be on a TON of book shelves. So yeah it's possible for folks to remember Bunker.
