Of possible value in this thread, RFC 7719 has a bunch of definitions of DNS terms. Here's what it says about "wildcard":
Wildcard: [RFC1034] defined "wildcard", but in a way that turned out
to be confusing to implementers. Special treatment is given to
RRs with owner names starting with the label "*". "Such RRs are
called 'wildcards'. Wildcard RRs can be thought of as
instructions for synthesizing RRs." (Quoted from [RFC1034],
Section 4.3.3) For an extended discussion of wildcards, including
clearer definitions, see [RFC4592].
All of RFC 4592 is about the use of wildcards in the DNS.
