Oxygen is required at 15000’ but not at 14999’...I’ve been to 17000 w/o oxygen with 40 others in a DC3. It was a slow forming location as everyone was a little logy for the first half minute of a 90 sec freefall.

You are pushing it with 17000 in a DC3 however I was at 13000 in a DC3 and that in itself is a great "happy hour lala time".

BTW, a DC3 is a 26 max load limit via carrying capability aircraft...

I’ve snowboarded at 15k in Chile. Why do you need O2 at that height?

Either there is an exception for jump aircraft or the rule has changed since the early '80's. I've exited many DC3's and C47's with forty jumpers aboard.
