sure.  But the structure is not *refined with hydrogens* when they are
in predicted positions.  Following the same logic one could suggest that
electron density should be deposited, since we can approximate it.  I
think it's useful to limit the information presented in a pdb-file to
what was actually refined + specific instructions on how the refinement
was done.

I wouldn't call it a post-refinement manipulation, as nothing was really
changed (afaiu, in most cases riding hydrogens are placed automatically
by the program and not manipulated by user).  On a digressing point, you
might be underestimating the problem of "misinterpretation by
insufficiently trained people".
