Supersonic intakes and the hydrailic ramp mechanisms seemed like a lot of unnecessary weight to carry round but it was probably more expensive to replace them.
Tricky. I suppose it depends on how fast you could 'really' go with a typical load as to whether the ramps would be necessary to keep the shock positioned upstream far enough of the compressor. If it naturally stayed in an OK posuition, no need for the ramps I guess.
