What are the potential benefits of a 7075 welded frame over current alloys

If 6061 or 7005 were strength-limited in bicycle frame applications, using 7075 instead would be advantageous. I don't think they are, I think in most areas the limiting factor is stiffness, and all three alloys are basically the same in that respect. 7075 is very expensive compared with 6061. For bicycle frames, I think this one is likely to fall into the category of "interesting exotics" alongside Magnesium alloys, Titanium alloys and stainless steels, by being both more expensive and worse than carbon fibre.

Does it need heat treatment after welding? Cheap 6061 frames which haven't been retreated after welding tend to fail in the area affected by the heat of welding.
