I can't speak for ungoogled-chromium, but for Linux-libre and IceCat,
there's at least one other limitation in snippets that are preventing us
from using them: the names of the pre- and post-snippet directories must
be the same.  In the case of IceCat, that would force us to either (1)
mislabel the upstream firefox source as "icecat", or (2) mislabel the
transformed icecat source as "firefox".  Ditto for "linux-libre" vs
"linux".

     Thanks,
       Mark
