I initially had these changes depending on the typed urls revisit logic CL that
eventually turned into a creating a new component. Since that CL hasn't/isn't
getting checked in, this CL has been forced to sit by idle. So I'm removing all
the revisit changes from this CL (and fast-forwarded to HEAD).

Stan - I'm kind of assuming you don't care to give these changes another once
over. There are no substantive changes since the version you approved. Going to
send these to CQ if try bots look good.
