Unexpected behavior of identical() with language objects

I ran into this and found the result very surprising:
identical( quote({ a }), quote({ a }) )
# FALSE
It seems related to curly braces. For example, parens work fine:
identical( quote(( a )), quote(( a )) )
# TRUE
Is this expected behavior? I can't seem to find anything in the help
for identical that relates to this.
It's not in ?identical, but ?Paren gives you some pointers.
str(quote((a))) and str(quote({a})) are also informative.
