With the *ist's, you can just rotate the adaptor further to remove,
since the slower removal technique is intended for bodies with the
aperture simulator. I've no issue in mounting and removing lenses with
the adaptor staying on the lens. This is in fact the way the adaptor
normally stays, as I get a lot more use out of the 50/1.4 than the
135/2.8 I also own in M42 mount.

One adaptor per camera body in use with a screw lens is required. Whilst it's
recommended to mount the adaptor to the screw lens then mount the assembly on
the K body when removing the lens you simply unscrew it as the screw adaptor
becomes locked into the mount and has to be released. The normal lens release
button does not work with the adaptor.
If you wished to fix a screw adaptor on each of your screw lenses you'd need to
remove the adaptor locking flange and fabricate a locking pin hole on each lens
assembly that mimics those found on a regular K mount lens. It sounds easier
than it is because a lot of the screw mount lenses don't seat flat on the mount
so a piece needs to be added. More trouble than it's worth in the end. I find
using anything but A compatible lenses on my *ist D a PITA.
