ACMatch seems unnecessary here.  Perhaps
kDisplayTitleForCurrentUrl
?

And remember to revise the feature name string in the .cc file too.

nit: please add to the bottom.  (We've been working sequentially; no reason to
change now.)

When moving, be sure to move the instantiation in the .cc file too.
