anyone who doesn't fully exhaust their HSA by the time they die

Is that actually a meaningfully large group of people? I spend something like half to 2/3 of my annual HSA contribution every year, and I'm only 40. Odds are very strong that I'll empty the thing before I die, because my healthcare costs will go up and I won't be contributing any more. I didn't get the impression that I was a particularly isolated case, either.

Even if you expect to exhaust your HSA before you die, my proposed strategy still either beats or ties the “shoebox strategy” as long as you anticipate your HSA lasting through age 60, you're currently under 59, and you're not currently maxing out your Roth contributions.

If your older-than-60 self incurs medical expenses at least 7.5% of your gross income and itemizes, those expenses can be deducted—unless you used them as an excuse to make a tax-free HSA withdrawal. So if your future self is going to need the growth on today's existing HSA dollars to pay for medical expenses, you will still be better off burning any at-hand receipts to make HSA withdrawals today and coincidentally making Roth contributions of an equal amount. (And during years your future self is spending less than 7.5% of gross income on medical expenses, or fails to itemize, my proposed strategy does no worse than the “shoebox strategy”—you're still making 100% tax-free withdrawals from growth on money your past self had put into an HSA.)
