Something along the lines of "1 year of free upgrades, then upgrade pricing" is a good idea even without considering OS compatibility.
It keeps customers who bought just before a new release happy, and removes anxiety about whether you should wait until next release to buy.
I would hope that, for a period after it was known that v4 would not support High Sierra, they were given either a refund or a free upgrade to v5.
