That will indeed boost Earth based telescopes.
I even think that the 39m E-ELT (cost $2 billion) will outperform the JWST (cost $10 billion), not only because of its much larger aperture: 6 times bigger == 36 times light collection surface.
And I doubt whether the conceptual HDST possibly planned to be built in the 30s as a successor of the JWST will be ever built. A 100m OWL optical telescope which was canceled due to technical design problems in favor of the EELT would have more chance in the 30s due to improved technologies compared to the 00s (30 years ago).
Bottom line: Earth based telescopes are MUCH cheaper to build and atmospheric turbulence is not a big problem anymore. Only sky coverage is a disadvantage as these telescopes miss a part of the sky close to the opposite celestial pole, but that is usually less than 15%.

At over 3 times the aperture it had better rival the 25 year old rust bucket

I think Damien did one of the Gliese 581 exoplanets that looked like that...

That's an amazing image for a ground based observatory. The other advantage of a space telescope though is no light pollution and no weather.
