Indeed.  And the reverse is true as well: while it might be OK for
a user to put his open-parens in column 0 to help Emacs be more
responsive, it's not OK for Emacs to be too slow on files where there
are no such open-parens in column 0.  So Emacs has to use some other
mechanism anyway to avoid the slowdown in such files.  Once you have
this mechanism in place, the "open-parens in column 0" heuristic is just
not worth the trouble any more.
