Alright.
I was also going to question the use of term “Modern Classical Composer” since it can actually mean a lot of different things.
After all there are plenty of talented and successful modern classical composers who do not consider using unconventional techniques (be it playing or writing) experimental or distasteful.
Simply because as we all know and realize there is no such thing as truly conventional or experimental.
Those are simply the terms that define a temporary stage of any self evolving process and development.
Whatever is conventional today was once unorthodox and experimental and so on.
This even applies to instruments and their development that often leads to birth of new instruments that are made to work with specific styles of playing best.

I just hope one day Gibson or PRS or even Fender come up with a fretless instrument with pick ups and sensors specifically designed to work with Glissando technique.
There have been several atemts…
In the world of today where software and computer manufacturers put their resources into development of a ****ing toilet seat with built-in internet browser anything is possible LOL.
