This is not true. It would be possible to describe behavior in prose too.

Indeed. Many of these end up getting used in new specs because they
are readily available in WebIDL :(

Going through these would also bring up a healthy debate about what
patterns in legacy APIs are bad ideas to keep using in new APIs. I
personally think that 'stringifier' is something that should be marked
as legacy and a bad idea to keep using for example.
