Agreed.  BTW, we now also have `window-system-default-frame-alist' which
is not consulted by these either.

You can test this if you replace, in `modify-all-frames-parameters',
`setq' by `customize-set-variable' as you suggested earlier and then
remake Emacs.  On my system making aborts with the "Attempt to ..." bug
mentioned above.  IIUC, someone noticed that this could constitute a
problem for the scroll-bar case and handled this by introducing
`scroll-bar-mode-explicit' but didn't care about doing the same thing
for fringes.
