I think they're rare because up till very recently we catered to
pre-C99 compilers that wouldn't accept them. There's not much
point in insisting on that now, though.
Personally I'm less excited than Thomas about trailing commas
being good for reducing diff noise, mainly because I think
that "add new entries at the end" is an anti-pattern, and
if you put new items where they logically belong then the
problem is much rarer. But I'm not going to argue against
committers who want to do it like that, either.
