Overall, this proposal start on a good idea but its execution is off, mostly because it mixes/misses several independent problems which could each deserve their own MSC potentially:

• Defining a new 3PID type
• Defining how such 3PID can be validated by an Identity server within an association session
• Defining how such 3PID can be added to the Homeserver user's administrative contacts
• Defining if and how this new 3PID can be used with Homeserver authentication

@maxidor Thank you for your input!

I have removed the parts relevant to the authentication flow and just mentioned a potential authentication flow as a motivation for adding DIDs as a new 3PID type.

I hope to address your comments about authentication in the new MSC for authentication.

@friedger Looking good! And definitely something that I could turn into concrete implementation. Good work! Looking forward to your other MSC.

@turt2live @maxidor I have resolved the open conversations with comments.

• Defining how such 3PID can be validated by an Identity server within an association session
• Defining how such 3PID can be added to the Homeserver user's administrative contacts

These require new MSCs.
