Current ARIN policy contemplated as much as a /12 per provider and set a cap there allowing a provider that needed more than that to only get additional /12s rather than nibble boundary round-ups. Owen

I’ve tried several times to come up with a scenario that leads to depletion in less than 200 years, and I haven’t managed it. Can you do it?
during some ARIN discussions that revolved around Transition Technologies and allocations to large ISPs, there were more than a few folk batting around the idea that they may need to allocate a /24 or a /20 even to a single provider.
I believe DT has a /19 assigned to them currently? how many /19's are there in the v6 space? (524288-ish) That's only ~100x the current number of active ASN in the field. It's unclear (to me) how many of those could/would justify a /19 equivalent, and how fast the ASN field is growing over time.
200 years seems optomistic, 20 years seems easy to imagine surpassing though. What's the sweet spot?
