Does the Blender dev process include user/usability testing?

The Ideas here are regressions of the current workflow since right now the Blender Institute among many other professional developer teams are always seeking and preferring communication with short paths with clear input and valuable data.
Quality over quantity.

Already mentioned it in the Blender 2.8 development thread
Blender 2.8 development thread - #6263 by myclay ;

Seasoned Artists capable of producing higher quality output with Blender are in teams and giving direct feedback to developers while being in the same building.

THIS is one of the most valuable ways to optimize and gather quality input + you get promotion material for Blender. its a true win.
