Mount rotation on 645 to K adapter

I have recently acquired some 645 A lenses and the original Pentax 645 to K adapter. Can someone enlighten me on the purpose of the mount rotation feature (the one that culminates in a screw that makes mounting the adapter rather not-so-straightforward)? Do some people want their lens markings on the side? Or is it just to add some fun to the otherwise dull task of mounting a lens? Any ideas would be appreciated.

You can rotate the camera between horizontal and vertical shooting when mounted to a lens with a fixed tripod socket.

It's to dent your shiny new K-5II should you try to remove the adapter without remembering to rotate it safely away first.

Can happen to (still) shiny old K-5s as well. :-(
