This is intentional. In order to make thumbnails, it would have to read the entire files from the device over the slow MTP link. Most people would be very unhappy about that because they wouldn't be able to do anything else until everything is read from the phone.
The same can be said about other networking protocols, which is why we had options to display them, or not, and let us make the choice about consequences.
Trying to find a photo from a phone is a pain, they don't have useful filenames. You've got to go trawling through them all to find something. If you're organised, you might move photos into sensible folder names as you go along. And you might decide that it is worth turning on thumbnails to find the specific photo out of 20 from last week's birthday party.
If you read the context in the gitlab issue I posted, basically performance is terrible when previews were being generated. Someone complained (back when it was originally filed) that it should be controlled by a setting and the Nautilus/gvfs developers chose not to.
The only way it’ll be switched back is to open a new issue, perhaps with a merge request with code improving the threading performance enough to make thumbnails not bring the whole interface to a stall.
