@DhiyaneshGeek, thanks for the merge. I'd prefer you to review my code instead of modifying it directly next time. Your changes reduced what the detector can do.

See above, this is not just for Synapse. Moreover, the fact that the federation endpoint under _matrix exists (at Matrix spec level) is much more robust than matching a string.

Thanks !
