Yes, they seemingly solved one issue of several issues.

What happens when playing the following chord

A7#9
  e a d g b e
6 | | | o | |
7 | | o | | |
8 | | | | o o

and while holding the chord bending the b and e string at the 8th fret?

Keep in mind that using a divided pickup it's possible to e.g.
use modeling for the e, a and d string, e.g. a neck pickup of a
Stratocaster, with a Drop D tuning (while the guitar is a LesPaul not
tuned to a Drop D tuning), while the g, b and e string send MIDI
messages to 3 different MIDI channels.

Perhaps if the purpose is sending MIDI events only, but a guitar synth
provides more. You individually could change the volume and tuning of
each strings output, you could change the velocity curve. Some sounds
such as a lead synth allow pitch bend, while bending a guitar string,
other sounds, such as a grand piano don't allow this. In addition you
could mix it with all kinds of modeling.

Yes, but it could add endless sustain to a note and by a three position
switch fade to 2 different kinds of harmonics to simulate feedback.
