However I'm guessing that this initiative has probably close to no leverage on the EDA vendors & the fabs, so at best we'd get the RTL source.

This is the money quote. Australia messed this up so badly when they stopped supporting local car manufacturing. The point isn't the jobs, the point is keeping hard earned competencies.
