The thought process is wrong.
I would appeal to the decision-makers in F1 to look at the following case study: BTCC vs. ATCC/V8 Supercars.
In the mid/late 90s the BTCC was enjoying a golden era of popularity with races being watched by mainstream audiences and the series attracting serious manufacturer participation, Since then it has introduced gimmick after gimmick: Shorter races, reverse grids, suspicious late-race safety cars for "debris" that are actually designed to close the field, success ballast, balance of performance. It has also moved onto a channel that far fewer people watch. Result: a massive decline in interest from televison viewers, a modest decline in attendances at the circuits, and an almost total loss of interest from manufacturers (in terms of works entries, at least) and from top international drivers.
Contrast this with V8 Supercars where they have generally maintained the same racing distances per weekend (sometimes splitting them into more races over shorter distances, but still much longer than BTCC events), but they have ensured that all starting grids are determined on merit after a proper qualifying session, there's no BOP, no ballast, no nonsense. Basically no (or very little) dumbing down. And they've managed to stay on Channel 7, which people actually watch. Result: it's still incredibly popular in its home market, it's attracting new manufacturers, and as anyone who has been watching this year will tell you, it still produces great racing, which is all the better for being real rather than contrived.
F1 is going down the BTCC route. It's maintaining most of its fanbase anyway because it started from a position of such overwhelming dominance that there is no other single-seater championship that can challenge it. But it still faces a potential sharp decline in popularity if it continues down the road of dumbing down, if you ask me.
On the specific issue, fundamentally we have to ask if Safety Cars are intended for safety, with the minimum interference in the race, or if they're there for entertainment and to create overtaking opportunities. If F1 is a sport, the Safety Car is there for safety and it will only be used to protect competitors and marshalls, it will then be withdrawn asap, lapped cars will remain lapped, and the race will pick up where it left off. The loss of earned gaps will an unfortunate side-effect of this process, not the aim. If anything else happens, we all have to face up to what we've known for a while; F1 is not a sport. Not a pure sport, at least.
