Seriously, this is a particularly important debate now. The elites are about to lose their funding, and they'd better engage with the rest of us sharpish if they want any money at all. So thanks at this point to Edinburgh Centre of Excellence for the Scottish Nights Map
I've never been involved with any squad or elite committee, but I have organised a lot of elite races, and I know many of the elites quite well. Even Mharky thinks I know what I'm talking about

Start location
Drinks controls (when not needed on other courses)
Separate start block
Mapped warm-up area
Different map scales
Unshared controls
External (and late) control on start times.
...
Some of these have gone away down the years, but the defining features are what mharky said "Those decisions are made by old men on committees." and from the athletes "we never asked for it".
Many of the elite athletes are a bit self-centred (though curiously, this doesn't seem to apply to the very best ones). But what they don't get credit for, because it is slow and indirect, is the pressure on everyone to drive up standards. Without the elite we'd all be running round in football boots, cotton kit with OS-based maps and pin punches.
