No, because of this:

DEFUN ("frame-parameters", Fframe_parameters, Sframe_parameters, 0, 1, 0,
       doc: /* Return the parameters-alist of frame FRAME.

[...]
  alist = Fcopy_alist (f->param_alist);

No, it's autoloaded.

Right -- I don't really know how the face/frame stuff actually works.
If it was a very general problem, then surely we'd stumble across this
whenever we make a new frame.  But the bug seems to manifest only on
terminal frames -- when we change the background mode.
