... which was pure security theatre that made it look more obfuscated to 
the untrained eye, but would never fool even the simplest automated tool.

It is important to remember what PGP is for, and what it is not for. It 
is most definitely NOT for hiding metadata. No system based on email can 
ever do that, so it is safer not to pretend otherwise.

If you need to hide your metadata from the state on pain of torture and 
death, PGP is NOT the solution. Use Tor, use Signal. And even then 
you're taking your chances because in many countries it is highly likely 
that your endpoint is rooted, and no security software can protect you 
from an pwned endpoint.
