>From what you've said, it could be that crematoriums were already operating just below capacity and are now just above capacity, causing growing backlogs even with only a very small increase in demand.

Can't be the case throughout the country in all affected districts and all densely populated states.

You see reports of crematoriums running 24/7 and still not able to fulfill the demand for cremations and find it reasonable to land on any other conclusion but people are dying. I think I've presented enough.
