I’ve always had saw blades(carbide)sharpened by cleaning up the face, now the place that sharpens cleans up all four faces so that after several sharpenings there is little kerf left and the top of the carbide has been ground down so much that the carbide is level with the blade stock. This doesn’t seem right to me, even though they say they do this with all sorts of highly technical equipment. The blade that came back recently has carbide about 1/32 thick, about 3/16 long and virtually no kerf clearance. What’s with this?

ya - well -
I think you need a new sharpening service that understands wood blades - only reason to do what they describe would be if the cutters were badly chipped -
"only reason to do what they describe would be if the cutters were badly chipped -"+one more reason: they sell blades.
My guy wire wheels the sides for cleaning, faces the tips and tops only.
I'd be po'ed if they were messin with the kerf thickness, I depend on some things being "just right" and some blades, such as those that would cut a fret slot at .022 HAVE to be maintained at that set.
Find a new sharpener or have him retip when he grinds them into binding..for free.
