Yes, I agree. It's weird, especially since is_map/1
and is_list/1 are exported and have definitions in the
erlang module.

But since the documentation explicitly says that
erlang:function_exported/3 does not return true
for BIFs, and since it has behaved this way since
ancient times, we don't want to fix it in a minor
release. So we will fix it in 18.0.
