It seems to me that IFR GA capable a/c are pretty much a minority.
They are perhaps, yes - yet Rod1 is right. Those owners/operators/pilots are under much increasing pressure, given the sharp raise of rates at commercial airports (often cleverly disguised as 'mandatory handling') which itself follows from the success of so-called low-cost airlines. They have less and less aerodromes available, at more or less bearable cost.
We (owners/operators/pilots of less impressive planes, like Rod1 and myself) would be short-sightedly stupid to disregard their problem - what happens to them today may well happen to us tomorrow. And even if their needs and issues are not the same as ours, they are our "nearest of kin" so we do should share their concerns.
