It's much easier to code 'image to selection':
c = pdb.gimp_channel_new_from_component(image, GRAY_CHANNEL, 'TEMP IMAGE2SELECTION')
image.add_channel(c)
pdb.gimp_selection_load(c)
image.remove_channel(c)
gimp.delete(c)
'layer to selection' is:
pdb.gimp_selection_none(image)
buf = pdb.gimp_edit_named_copy(drawable, bufname)
c = pdb.gimp_channel_new(image, image.width, image.height, bufname, 50.0, (0,0,0))
image.add_channel(c)
fsel = pdb.gimp_edit_named_paste (c, buf, False)
pdb.gimp_floating_sel_anchor(fsel)
pdb.gimp_selection_load(c)
image.remove_channel(c)
gimp.delete(c)

I don't think so, but it might be nice to have a "layer to selection"
filter that would create a selection from the gray values of the
active layer.
