You're certainly entitled to your opinion, but I judged the previous
behavior a bug (helped in no small part by the number of bug reports
I received about it) and fixed it. It defied user expectations and
was not consistent with the treatment of $(...). When I fix a bug,
I don't generally add an option to enable the old behavior.
(Yours is the first complaint I've received about the change in the
year-plus since bash-4.0 was released, by the way.)
