Sure. I just checked OpenBSD 3.4, and its yacc has this extension.
And its yacc did the right thing with a comment containing "{", too,
so Bison is compatible with its yacc. The proposed patch would break
this compatibility.

Often people don't complain. They just use yacc instead, and don't
bother with Bison. See
<http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00031.html>
for the most recent example of this, dated yesterday. Nelson
H. F. Beebe wrote to me privately and said that he has given up on
Bison for compiling several yacc grammars.
But this doesn't mean we should stop worrying about yacc
compatibility; quite the contrary.
