I don't think I made a conscious decision about this when writing the
code, so if there's any dissimilarity between this and other things
it's probably unintentional. I don't use $WIDGET myself in my callback
either. I think I just copied the part that sets args[0] a bit blindly
from another callback, but in that one I bet it uses initthingy->nam
for the rthingy_nocreate() call too. So to summarize, feel free to
change it.
