This is specifically for bringing in people with technology skills (as has long been done with doctors, dentists, etc). They want to expand that to computer skills, and raise the top rank to O-6 (colonel).
Better would be to just have special high-pay technical specialist ranks.
Just keep them as GS pay-grades. Not rank.
Bad enough when nurses come in direct as 1Lt and Docs as Capt.
They are not officers, not combat line people.
See no reason to change the GS scales to actual ranks.
