Should I create a Jira issue for that task?
Or will you anyway implement something in this direction?

Support for prompt=select_account will be cool. Another suggestion for
adding query parameter for skip some mechanisms (like
skipAuthMechanism=cookie,kerberos ) might be good too.

That'll only make sense if we also add support to allow multiple accounts, which could be fairly easy on the server-side, but much harder to support in adapters.

Not sure if we need to support both, but IMO it will be good to have
solution not tightly coupled to Kerberos. I can imagine similar
situation with other login mechanisms as well. For example with
authenticating users by certificate, admin may also want to skip
automatic login with the certificate from his browser and instead login
with username/password form.
