That's great to hear.

The conversations around the activation of Taproot have far outgrown a single IRC channel, let alone a single live 
conversation. Nor is having a discussion with under a few days latency "coming out of the wordwork weeks later". 
Frankly, I find this more than a little insulting. Bitcoin's consensus has never been decided in such a manner and I see 
no reason to start now.
