Right, I forgot the final option, which is "regular gamma compressed TIFF, but in a DNG wrapper", which is what you say you are using. I’m no sure what benefit this DNG wrapper gives, but from my earlier experiences with DNG ("I think it should have the metadata that specifies it is linear, but why doesn’t it work?") I just stopped wrapping in DNG and just went for TIFF. I see no benefit in DNG and it just makes everything more opaque.
The whole Output tab in VueScan is a complicated nightmare.
Anyhow, ACR can store its non-destructive edits inside of the TIFF file as this Adobe XMP stuff, and that is all I need.
Here’s an example from the end of a TIFF file from today:
