Technically, nothing prevents you from extending Basic Auth and to make it a usable better auth protocol.
You could write an extension and make a case for login/logout/session management and/or generalized hotkeys and go with that into the w3c or ietf to propose an auth mechanism.
I mean, it can be something as simple as having more meaningful aria-attributes on the HTML tags that you parse out and make usable via hotkeys.
It's hard to talk about an idea not yet finished enough so that it can be specified, but I'm sure there is a HUGE need for accessibility improving browser extensions to begin with.
