Austin's Meuller could be a vital and effective General Aviation airport, and its existing runways and taxiways are thoroughly adequate- indeed, excellent- for that sort of use. Unfortunately, for reasons having everything to do with politics and nothing to do with practical reality, it will never be.
"But having had lived in Austin the last 11 years, if they reopen Mueller it would be a disaster. It's in the middle of some very densly populated areas. It doesn't have enough space for a decent sized runway. (Bergstrom's runway is 13400 from threshold to threshold). Parking in the area is non-existant. Other GA airports exist in the area."
The area is an essentially perfect location for a GA airport, with plenty of land for that limited use. It is bounded by I-35 (what is it there, 10 lanes plus feeders?) and the Morris Williams golf course, hardly "densely populated," and certainly no more densely populated than any other in-city area. There is no doubt that, as the air carrier airport, Meuller had outlived its usefulness; as a GA airport, it could and would be perfect, and the grounds of the airport provide plenty of land for a robust, well-run GA airport, and many other uses besides.
What is most confounding, however, is the claim, "Other GA airports exist in the area." Where? Have they just been hiding the fool things from me? I'm so dopey that, the last couple of times I flew to Austin, all I could find in the way of airports were Georgetown (29nm from AUS), Lakeway (on the other side of Lake Travis from Austin), and Lago Vista (hell and gone west from Austin). Your definition of "in the area" must mean "in the same time zone."
Since Austin Executive (formerly Tim's Airpark) closed, friend, Bergstrom's IT in Austin, and if you don't have a champagne budget and an airplane to match, the GA facilities are terrible (trust me, when there are a bunch of King Airs, Citations and G-V's on the ramp, neither Gate One nor Signature is all that eager to beat feet to help the poor schmuck in a 172 or Archer; I know, one of 'em actually lost the Archer I flew there a couple of months ago).
Lastly, Meuller already has great runways, and no GA airport needs anything like Bergstrom's 13,400 foot, or its 9,000 foot, runway. FWIW, AA used to fly DC-10's out of Meuller's runway- guess that's "decent" enough sized!
Enough ranting.. Ciao.
