The reason there's browse-url-default-handlers and browse-url-handlers
is that the former is meant for Emacs itself and packages whereas the
latter is meant for the user to customize.  IIRC, Stefan Monnier
suggested that distinction back then when I added the handlers and I
still don't see a better way.  If there was only the defcustom
browse-url-handlers, either packages couldn't sensibly add to it or if
they did, users wouldn't be sensibly able to override what packages
added.  Or if a package added an entry which the user then saved, how
would that be removed when the package was removed?

That's different with display-buffer-alist which is nil by default and
it's not expected that packages add rules to it.  In contrast, if I'd
write a gemini client for emacs, it's quite obvious that I'd add an
entry matching gemini:// urls with my hander to
browse-url-default-handlers.
