Matrix >= v1.0.0 limits display name field to 100 chars #4634
Description
Sub issue of: #3387
Problem Definition
synapse >= v1.0.0 introduced (matrix-org/synapse@d16c637) a length limit on the User displayname field of 100 characters.
This breaks our use of this field as a way to publish hex encoded ecrecover signatures since those need 132 characters.
Possible solutions
- Get Matrix to change the limit: New 100 char display name length limit is too restrictive matrix-org/synapse#5870
- Switch to
base64encoding (which would fit at89chars for a signature) - Switch to use
avatar_urlfield which has a limit of1000chars
All but 1. would be backwards incompatible (which currently should be doable) and would need coordination with the light client (ping @andrevmatos).

Good news, the Matrix team increased the length limit to 256 chars: matrix-org/synapse#5906!
Now we only need to wait for them to make a new release. I asked in the linked issue if there's an ETA for that.

We upgraded to synapse 1.4.0rc1 for now.
Once 1.4.0 is released we can switch to that.
