Well, it could be done with an auto-command when the buffer is read
which you could put in your vimrc:

augroup AutoCenter
au AutoCenter BuffEnter * norm zz
augroup END

This would center on whatever the focused line is upon opening a
buffer (if possible). If you haven't specified a +{number} offset,
it's on the first line, so it won't lower that to the middle of the
screen because there's nothing above it. But if there is a +{number}
offset, it should center it on the screen.
