In my view, the standard is quite clear:
"If any character (ordinary, shell special, or pattern special) is
quoted, that pattern shall match the character itself."
That sentence applies to pattern matching notation as a whole. Bracket
expressions are a part of pattern matching notation. There is no
language anywhere in the standard that excludes bracket expressions from
the sentence quoted.
