After Argentina some competition pilots were quite disappointed
with the new variometers using acceleration to calculate lift. I
have not tested myself, just telling their opinion.

Regarding gusts, the Butterfly website (in FAQ) already claims:

"A conventional variometer uses changes in air pressure (TE-
pressure, static- and total-pressure) to determine energy
changes the aircraft experiences. Butterfly Vario does the
same.
Additionally it uses an inertial sensing platform that allows for
real-time determination of airmass-movement and realtime
determination of wind. With this technology a pilot can judge
the difference between gust induced energy changes and
thermal induced energy changes."
