This sort of proposal pressure (over 9:1 oversubscription) leads to very conservative proposals, where we request absolute minimums and emphasize that even a non-detection will lead to publishable science in such and such a way.
Getting over 60 orbits to point at a blank field would have been frankly impossible through the regular time allocation process, not because the science wasn't excellent, not because it wouldn't be recognized as excellent, but because it would crowd out other science that could be done with far fewer orbits per project.
The telescope administrators explicitly recognized this problem when they set up the Director's Discretionary Time process (and this is common to all telescopes now) - sometimes you need someone with the authority to just roll the dice on a long shot.

Too many times I heard things along the lines of getting "low hanging fruit" to get "published" and that "don't try that you won't ever graduate". Why is graduating and publishing papers and tenure and theses the goal of academia, instead of trying the highest possible risk things that even companies wouldn't want to risk? Why isn't academia about doing the most utterly crazy things possible in the name of advancing science for civilization?
Yet, what's good for the academic? Each effort costs potentially years of your life. A great discovery will catapult you to the stars, a small one will advance your career, and a negative finding does nothing. You're not alone, you have peers competing for the next round of funding, tenured position, or residency. There are literally never enough to go around, and each will judge applicants in part on their record of results.
I think you're describing a conflict between what's valuable for a system at scale and what's valuable for individual actors within it.
For topics with a large number of practicing labs that make use of relatively accessible tooling you might be able to pull off such an approach.
Other fields require customized, incredibly expensive instrumentation. Physics and certain areas of biomedical research are examples of this. It's not uncommon that fewer than ten labs in the entire world will have the capability to perform a particular highly specialized technique.
Even in the largest fields though, it will be your peers reviewing your grant applications at the end of the day.
What you don’t do is sum the 10000 different requests, nor the 100 requests that also want to use 100 hours each.
Novel trials are big risks, are institutional (or worse, multi-institutional), and searcch spaces are large, well-picked-over, and huge gains improbabble. Though aversion to novelty is a long-standing behaviour, see "Resistances to the Adoption of Technological Innovations", by Bernhard J. Stern (1937):
