Re: By all means 'extend' it for a short time
Live streaming was performed by some larger Parish and Town Councils before the pandemic.
In my Parish we have never offered it as we've only had "standing room only" on 3 occasions in the last 10 years.
I have recorded the Zoom meetings though, and it's a very good resource when checking the clerks minutes, and anyone can by law record the meetings, physical or virtual.
