Lot's of work has been done over the last years improve the default options for
general pupose cases. Have you open an issue about that one?

Have you considered using things like poudriere that would allow you to build
your own repository with your own set of packages and options.
You will benefit:
- ability to use pkg for your upgrades
- ability to use customize your packages
- safe rebuild process (in case of broken ABI)
