I'd really like the default to be FALSE, at least for the upcoming
release.  As you note, the change will cause vignettes to look
different.  There are over 260 vignettes in the BioC source tree and
given that most developers have little extra time, I would rather they
not have to review these docs because of this change.

I'm glad the feature is there, I think it is desirable.  I hope to
turn this option on when I write new documents ;-)
