Historical reasons, I’d imagine?

Doing a git-blame, it seems that ‘browse-url-button-regexp’ was
introduced in a32e1feb438e793a8378671c7124d226b58f65f0 [0], where Lars
refactored ‘gnus-button-url-regexp’ out from “lisp/gnus/gnus-art.el”
over to ‘browse-url-button-regexp’ in “lisp/net/browse-url.el”,
presumably for the very reason of other packages being able to use it
for controlling what’s considered a button.
