True, there was extensive effort, but wasn't the effort geared towards providing the deceased god a path back to the heavens or wherever they had come from?

So, presumably after they had ascended with the help of the burial provisions, the remainder of the body was irrelevant?

But perhaps this part was not clearly defined in the teachings.

I don't think so. Consider the effort to hide tombs full of gold and jewels. If the humidification was just a temporary expedient, wouldn't it make sense to loot the tombs once the soul had passed on, as a general policy?

I think they expected to be bodily resurrected at some future date. I think a lot of people today expect to be bodily resurrected at some future date.
