Description
Currently Tippecanoe only supports Web Mercator output. Support for custom tiling schemas would enable Tippecanoe to be used for use cases where a specific (often obligated) tiling schema is desired.
Implementing this functionality doesn't necessarily imply adding support for coordinate transformation as custom tiling schemas are usually defined based on existing projection systems.
For reference: the gdal MVT driver (https://gdal.org/drivers/vector/mvt.html) has a TILING_SCHEME parameter for this purpose.

Research direction
The issue points to GDAL’s MVT driver and its TILING_SCHEME parameter; begin there to define the expected schema options. Then locate Tippecanoe’s existing Web Mercator tiling path and determine the tests or entry points that govern it. Done means supporting custom tiling schemas without requiring coordinate transformation.
