There's so much to this, and more firewood and firewater has been consumed over such discussions since the glaciers receeded than any other. And not just archery.
The problem with working at the minimum fringes is that it does not allow any margin for error. If you're at the hairy low end and are cold, tired, tick a branch, snag a jacket sleeve . . . what then?
I've so far been hale and hearty enough to have always fielded a 50# or better bow and a middling heavy arrow when deer hunting. And even then I draw beyond that. Got as far as a 70# D. Quillion Patriot bow but never got good enough with it and did not enjoy shooting it so I sold it. But there's a lot of folks not able, for whatever reason, to get near that draw weight. The stern recommendation may be to find an alternative to a traditional stickbow. That's kind of harsh, but is perhaps what is needed for the betterment of bowhunting. But where do we draw the line and how is it to be measured and enforced?
Is a 40# bow and 560 gr arrow with a solid two-blade better than a 60# compound and a 360 gr arrow with a mechanical head? How do you measure impartially and fairly? Harvest reports? Loss/wound statistics? Good luck getting a concensus on that one.
One of the best ideas, I thought, is a proficiency test for a bow license. When I took my hunter's safety course it was optional - but with it I can (supposedly) participate in certain semi-closed areas. Haven't come across one yet (31 years later). Should it be manditory? Bring a broadhead and three field arrows and if you can penetrate some test media to XX inches with the broadhead and also hold a three-shot group of XX inches at XX yards with field points you get a passing grade. But who sets the bar? I'd go for that, even a four-year renewal requirment . . . if it was something I knew I'd pass. But if it was three shots in 6" at 45 yards? I'd be pretty upset.
'Course, I'd also be practicing a lot at 45 yards.
