Element have a perfectly good implementation written in Go called Dendrite. I run it. It's good.

But support is deprioritised in favour of Synapse (Python).

Moving the goalposts with Synapse does not rejuvenate Synspse, it creates a fragmented system.

Get used to being boring. I am not moving to an ever centralised Synapse only ecosystem - a single implementation is not a federated protocol. That the new Element mobile client only supports Synapse was a huge red flag.

If diversity in implementation is not encouraged with action I'm back to XMPP (+ Jitsi).
