It'd certainly be 'great' to provide all of those.

However, if people see the need for individual ones (e.g., "is the
target ELF"), it probably wouldn't hurt to add ones as the need is
discovered.

Certainly, I'm aware of a keen need for an 'is the target ELF' check
-- that information is encoded in Lots of places i've seen,
differently each place.
