Well, there is only *one* way to correctly render FreeType output,
namely linear blending.  This technical fact is out of discussion.

To globally adjust the output to your taste FreeType already provides
means to modify the parameters of the sub-pixel colour filter; it also
provides parameters to adjust values for stem emboldening at smaller
sizes.

No, v35 will stay.  In particular, it is needed for B/W rendering
(which v40 doesn't support at all).
