There have been no gismu officially added, but some people have proposed
ones for experimental purposes. While the gismu and cmavo lists were
baselined, they are on wiki pages and this has meant that people have
modified the baseline list without official authorization, but there is
relatively little that we can do about it at this point (we could put up
the old baseline list, but people would likely still modify it). It is
possible that experimental gismu that have been added are marked as
experimental in their definitions; I know that this has been done in the
cmavo list.
