It certainly can, it just won't save much code, because bpftool would still need to have a big switch over BTF type kinds to do JSON output. I can do such conversion, if you prefer. I'm also thinking about switching pahole to use this during BTF dedup verbose mode, if Arnaldo will be fine with changing output format a bit.
