Potential bug/inconsistency in auth-source netrc vs plstore backends

[Soham Gumaste]

Hello,

I am trying to patch the `oauth2.el` elpa library to better integrate
with the native auth-sources system so that functions like nnimap and
smtpmail can use it transparently.

I noticed the following inconsistency while playing with this: As
shown by [1], the netrc backend does not require :host, :user or :port
as required keys in matched results, however, the plstore backend
requires :host, :login: :port and :secret.

This is causing an issue for me as I would like to patch the oauth2.el
library to store the access token as a secret, but without any port
associated with it. The oauth2.el library already uses plstore and it
is the more convenient backend to use.

Please let me know if this is indeed a bug and the possible direction
for a bugfix patch if that is the case.

Thanks
