I thought we already did the mandatory TLS argument to death many times.

We added MITM in WinGate mostly because Google and FB went to https.  
Google and FB you may take a bow.

Does this improve security of the web overall?  IMO no.  People can now 
snaffle banking passwords with a filter plugin.

You really want to scale this out?  How will that make it any better?

You're suggesting anyone wanting to run an http2 server now has to 
purchase, and pay for the ongoing maintenance of a cert, and take the 
cost on additional CPU to handle the load?

Organisations have to live with the pain in the neck of deploying 
signing certs to clients, dealing with visitor devices etc etc.  This = 
reduction in user experience.

So, IMO making TLS mandatory = reduced security, worse user experience, 
and increased costs.

That's progress I guess.
