I think you don't find any discussion because in some quarters this
behavior is the only one that makes sense: "ASCII control characters"
is interpreted as "ASCII characters whose codepoints are below 32
decimal".  Which is why I prefer to amend the documentation to say
that, instead of excluding DEL explicitly.

Thanks.
