No; however there are not many vector tile formats publicly defined. MVT is good at what it does.
The generic vector files used in GIS (shapefiles, DGN, KML, GML etc) are not a good fit for tiles - they describe a specific classes of features and do not optimize for tiling (i.e. you must always parse the entire files without regards what extents you are really interested in) - which is fine for generic GIS usage, but not for end-user vector maps.
