My changes are not that elaborate, Im just trying to convince
auth-sources that the oauth2 access token is a "password"

I didn't take the ephemeral part into account. What I am doing is summarised as:
1) Change the default filename to be `oauth2.plist` instead of
`oauth2.plstore` as that automatically activates the plstore backend
in auth-info when the file is listed in auth-sources
2) Store the access-token a second time as `:secret`
3) Store additional data like :user/:login and :host

I can share my patch if you're curious but it really isn't ready/in
the hacking stage. Basically my reference point is to make it satisfy
the search query in nnimap.el/smtpmail.el which is my use case.

My roadblock currently is that the auth-sources-plstore-search
function REQUIRES that the :port also matches, whereas the netrc
backend has no such requirement. I could just save all the ports im
going to use in the plist file but thats really a non-solution and I'd
like more clarity on this discrepancy.

Thanks,
