Great - next we would update all relevant documentation with a deprecation note and a reference of that ticket.

Right now I am contemplating doing this in a single run, right away, instead of multiple phases. Multiple phases would  which would allow us to have that `libprocess` default without having to warn about it. 

What do you think?

We would ...
- add a comment note here
- add an SSL flags description note
- possibly have the flags validation output a deprecation warning
- anything I forgot here?
