When doing work which requires wheels off I just support 3 wheels on ramps and the one I'm working on on one of my 5 tonne Sheffield steel stands which have served me well for donkeys!! Only when needing to disconnect both sides do I use both axle stands freeing up the pair of wheels but I think that is a rare situation
Having said all that, if I am working at home my downward sloping drive towards the garage is actually a great help. I often drive onto the ramps at the bottom of the drive and the rear wheels are up on the slope giving me ample room underneath and the advantage that the ramp height sets the car almost level which is handy for draining oil etc.
