I did this too until very recently as well. Finally got around to just setting up a docker image serving data from ~/Sites. I think it was the switch to an unexpected php version which convinced me.
I've just taken a look through /etc/ for anything else I may have configured which got lost. Doesn't seem much I touched myself, but seeing lots of files like /etc/shells~orig and /etc/syslog.conf~previous which are odd.
Would I be posting from jail?
Also, Apple has shipped 3 emergency OS updates (3GB each) in one month now. This is bad news.
