The engine doesn't do anything specific for blwf, so whatever you put in your
(contextual) lookup is what happens.  pref is different since the engine does
reordering.  But it only does the reordering if the virama,consonant have
ligated.  So, again, yes, you can block the reordering using a contextual lookup.
