Oh, totally agree. Discovery is awesome, user-configuration is insane. I
don't see there's any valid argument the other way.
Practical experience with SRV has shown that, whilst it is fine for large
service providers to do that sort of thing (c.f., Google, iCloud etc), the
practicalities of actually being able to setup SRV records and have proper
SSL cert validation is heard, particularly for "hosted domain" type
applications.
Having discussed with several engineers who have implemented SRV it is
clear that having each app do it separately is problematic because there
are a bunch of awkward issues. Not in the least is the simple issue of even
getting SRV from standard DNS libraries (e.g. one Android developer
mentioned that the size of his app increased significantly when he had to
bring in libraries to do SRV). Then there is all the certificate
verification stuff that needs to be done to properly implement discovery.
Overall this is much harder than it needs to be, and other non-standard
approaches have proved that.
