enhance a input.mbtiles file

EDIT: enhance a input.mbtiles file. Meaning do the tippecanoe magic on the layers it find for example simplifying or filtering geometrie and adding zoom levels that don't exist

~~Was wondering if we can use https://github.com/mapbox/vector-tile-spec/blob/master/2.1/vector_tile.proto not only as output but input format to~~

The request concerns enhancing an input.mbtiles file and references vector_tile.proto as an input format, but names no source files, tests, or entry points. First clarify the intended layer simplification, geometry filtering, and missing-zoom behavior; done would require an agreed scope and tests for those cases.
