.DS_Store, .fseventsd, .Spotlight-V100, .Trashes, and ._this and ._that
These can all die in a fire too, as far as I am concerned. macOS loves to treat the user's filesystem as its own personal garbage dump.

thumbs.db and those weird MS alternative stream files for recording origination.
filesystem attributes are for decorating files with meaning. Anything else that attempts to use filesystems in "interesting" ways is silly.
Apple and MS really ought to consider why they do this sort of fragile, idiosyncratic nonsense.
But... thumbs.db is precisely not an "attempt to use filesystems in "interesting" ways" — it's literally a just hidden file with previews stored in it. Storing the preview in the alternative stream of the file with the picture itself would be "an interesting way".
Agreed. Where else would you put that stuff? It’s gotta go somewhere, and this is the least surprising place IMO. Anywhere else would have to be a parallel store that follows filesystem mounts and unmounts, renaming directories, etc so that it alway perfectly mirrors the thing it’s configuring.

In the particular case of thumbs.db, storing them in NTFS alternate data streams would have been a good idea; they're essentially caches for the main data stream, so if they fail to copy to different filesystems it's totally fine. Of course, that wasn't viable because 1) IIRC that was before the widespread adoption of NTFS, and 2) they probably still need the cache somewhere for vFAT USB drives.
And .DS_Store is just your folder level preferences in Finder. If you don’t use Finder they won’t be created

Windows has been storing thumbnail cache in the user profile folder since Vista (2006).
It's been 20 years. Time to let it go.
OTOH, If you want the information contained in those files, where else would you save it?
To me it seems more sensible to store information relevant only to this OS in a specific cache somewhere within that OS. It would even make cache-like functionality such as evicting old entries super easy.

For most of these files, this isn’t information that can be reconstructed, so caching isn’t an option.
Also, the information has to move with the disk, if it is moved to or mounted on another system.
There are some tradeoffs. Like if you used a usb and set up folder colours or any of the other things stored in the file, they would not move along with the usb when used on another computer.
