Ability to disable all identity server functionality via the config file

By setting the default_is_url to an empty string/null or something.

Interesting. What consequences would this have?

Threepid invites wouldn't work; what else?

Also, just so I'm not guessing, what's the reason behind this?

[turt2live]

Someone wanted it for privacy concerns (I really should have linked the message). They were concerned that their users would accidentally use the identity server in a privacy-centric group.

The other thing (that I know of) to disable would be adding/editing 3pids.

Is there any movement here? I'd like to add that using the .well-known/matrix/client stuff for it would be very convenient.
For example by "m.identity_server": { "base_url": "" }

As a work around I've notice that having an 'identity server' that just replies an application/json {} in https://example.com/_matrix/identity/api/v1 works to keep riot happy and don't use an identity server.

But will be really nice to get an official way to disable the identity server.

Would also be nice to have this when the identity server you wanted to use is down :)
