I do some 3d modeling on the side with my side project (https://roguestargun.com), and I suspect those 800 polygons with good topology may be more useful to a lot of 3d artists than blobby fully textured SDF derived models.
A low poly model with good topology can be very easily subdivided and details extruded for higher definition ala Ian Hubert's famous vending machine tutorial: https://www.youtube.com/watch?v=v_ikG-u_6r0
And of course I'm sure those folks in Shanghai making the Mesh Anything paper did not have access to the datasets or compute power the Meta team had.
