Why bother, some ask?

Well, wide angle lenses really are hard to focus...

Because it would be a lot cheaper than investing in
an AF kit in medium format just 'cuz our eyes are getting older and less
flexible ;-)

You should be able to adjust your viewfinder diopter + glasses combination
so that you can focus on the screen. YMMV, but I find that even with
glasses, adjusting the diopter setting is both important and helps a lot, at
least with faster longer lenses. I have varifocal glasses, so I have to be
sure to always use the same section of the glasses for viewing.
