This is due to the following two reasons:
1. it's very out of date compared with current ports tree (like by 2+
   years!)
   - some of the ports here were mainly just updates I didn't upstream,
     which have since now been part of openbsd, like verilator
2. removing dependencies is a lot of headache to stay in sync and/or for
   ports I no longer use
   - e.g. dbus is very difficult to remove in a desktop while patching
     to remove from gtk and downstream
   - I don't want to spend more time reducing number of dependencies
     when I can be working instead. I no longer have as much free time
     as I did in high school :(

It was previously over 8 years out of date...
