I notice that files get marked for pending rewrite (yellow pencil) with the reason being
XMP::xmpMM\InstanceID
Is this something new Imatch generates? And when?
I've noticed this also, along with some other tags. I've ignored it, but assume it's from some recent ExifTool update?
This id must be added/updated when XMP data changes. Totally normal.

But new in 2021?
(I did read release notes - no mention though.)
