We already have list_is_last(), it makes sense to also add list_is_first() for consistency. This list utility function to check for first element in a list.
Honestly, I think we already have way too many of these kind of helpers. IMHO they don't really help, they hurt readability. You should know how the list works anyway, and if you do, then it's a no-brainer what's first and last. If you don't, then you are bound to screw up in other ways.
