I have never tried to dispute that it is documented.

The issue is not prefix argument and not namely aligning tags, but a lot 
of modifications scattered across file being invisible in the active frame.

I do not remember if I had problems due to C-k, but adding some friction 
to C-w and M-w if the mark is too far away is in my plan. Fortunately I 
usually can notice that C-w deletes significant part of my file because 
mark was set in other window. So undo helps (attention is required 
however to not revert undo to redo and to stop at proper point). Since 
adjacent region may be unfolded in response to editing action, sometimes 
it is hard to figure out if effect of key hit is consistent with 
expectations.

Since nobody joined to the thread, I assume it is my personal pain, 
perhaps related to Vim, perhaps to other experience. I can not say that 
I am investing noticeable amount of efforts to eliminate it, but I hope 
I will get better ideas in future.
