Isn't it quite common to have /boot on an unencrypted partition?

How would the update affect stuff like a GoCryptFS volume which I mount and use periodically but not all the time? Would those files be processed much faster than previously?

I used to have custom ROMs on my phone. It was a good learning experience and I got a fair bit of enjoyment out of it but I don't have the time now, either.

I did it for privacy and performance purposes but I gather that we are screwed in terms of privacy by using any android phone, nowadays.
