I don't quite understand. Without (my own) copies of the babl object?
Maybe types would be a better example. If I understand you right I can
do this:
Babl *format = babl_format("R'G'B' u8");
...
if(babl_format_get_type(format) == babl_type("u8"))
{
/* u8 type */
}
else
{
/* no u8 type */
}

Then it looks like I have to remember the formats of all created fish
myself :(
