Hello Alex,
The idea is (as I understand it) that every function should accept any
map and pick keys which it understands. If some keys are critical, then
they should be marked as such in the spec.
Function might iterate over keys and raise an error if there are keys
which belong to the namespace function cares about, but the names are
not known, but it is outside of spec's functionality and ought to be
done manually.
Best regards,
Mikhail.

Yes, and from the general standpoint of map handling I understand
that.
From the standpoint of functions that take options and don't pass
option
maps through to other functions, I disagree with the clojure
philosophy
here. So many bugs could be caught if we flagged unexpected map keys
when
they're used as options to functions. Of course use and validation
via
clojure.spec helps too, but from a general bug catching standpoint I
believe there's a huge value to flagging inputs to functions that
aren't
recognized by the functions.
