Celestalon had a twitter exchange that brought up the popular topic of Demo tanking and he used it to clearly disect why there are no Demo tanks, and why their implementation is not as easy as some people think it might be.
You can see the exchange here: https://twitter.com/Celestalon/statu...21582647853056
I'll put most of the tweets here as quoted bits:

I think we can safely state that with all this it is highly unlikely we'll see Demo tanking any time soon (if ever), considering the amount of work and re-work it would take to get all of the things Celestalon mentions.
If anyone still thinks Demo tanking should be a thing, they should probably be directed to this list and start working on a list of answers to what Celestalon has said.
