IIRC Camellia is more equal than the others. In particular its
inclusion in NESSIE and broad adoption make it a plausible "backup"
block cipher after AES.
So while we can consider dropping many of the more obscure and
obsolete algorithms, Camellia is probably best retained.
It is not clear that Intel et. al. will devoide any chip real-estate
to supporting it in hardware, so it will not be quite as attractive
as AES for most users, but it seems to be a fine cipher in most
other regards.
