Feature request SCRAM-SHA-256

[Tributh]

Hi,
is that here the right place to make feature requests?

dovecot supports as authentication mechanism
SCRAM-SHA-1 from RFC 5802
which was updated to
SCRAM-SHA-256 in RFC 7677

Can SCRAM-SHA-256 be added to the authentication mechanisms?

I would not like to request, that SCRAM-SHA-1 will be exchanged by
SCRAM-SHA-256, since several applications only support SCRAM-SHA-1

Regards

Torsten
