I think that problem exists for the constant spending model too. Probably all models. LTC or major health related events need to be addressed. In the Bernicke or constant spending model, I would want to know that I’d have a pretty significant sum left in my later years that would essentially be my LTC insurance. If I don’t spend it, it would be my estate/inheritance.
For us us a natural decline in spend with aging, a la Bernicke, would go a long way towards paying for several years of ltc. But obviously depends on your initial budget and how much travel and other btd stuff is in there.
