Yes many futures are not "cash settled" but settled in the actual commodity.
This is why in rare occasions the price of a thing goes negative because trading in that thing you are contractually obligated to take delivery and people trying to unload that obligation sometimes can't find buyers until they are paid to take delivery. It happens when nobody really wants to buy a thing and there is no capacity left to store or ship. When you buy a futures contract and you don't want delivery you have to sell it to close your position, and rarely you have to give people large sums of money so you can close.
In 2020 some Oil futures were negative at close, which has one obvious effect (if you're stuck holding the bag you're paying to store all this oil despite it being, at least temporarily, worthless) but also messes up the ETFs.
Suppose my actual oil futures go from $800k to $900k, the ideal ETF is trying to ensure that $800k also turns into $900k just as if its investors were in actual oil futures. But these aren't futures and don't result in delivery - so critically when real oil futures blow up and that $900k turns into -$1M because the global economy had a heart attack the ETF cannot be worth -$1M as it's just paper and I don't have to pay you one cent.
For the ETFs this means a negative exposure for the operator - they're eating unlimited downside but can't pass that on to their customers, and for a blip like 2020 that's survivable (if you're well capitalised) but longer term it would be fatal.
