This seems like a good move to me.
To be sure to understand, private IP address servers will not be able to
opt-in to be accessed by any HTTP origin.
But they will be able to opt-in for specific HTTPS origins.
Is it correct?

We have metrics in place telling us that ~0.1% of page visits at most make

Do you know whether these 0.1% happens more often in corporate networks?
