Description

Even though `makevtile()` supports uncompressed PBF data, the code at https://github.com/mapbox/tilelive-vector/blob/master/backend.js#L113 only allows compressed data to be treated as vector tiles. There are several cases when vector tile gets uncompressed and processed by other layers, and they have to be re-compressed just so that tilelive-vector handles it correctly.

Should there be a header or a URI parameter to allow for this?

Research direction

Start at backend.js line 113 and inspect how makevtile handles uncompressed PBF input. Determine how the issue’s proposed header or URI parameter would signal uncompressed vector tiles, then verify the rendering path handles them without requiring recompression. Done means uncompressed vector tiles work correctly through tilelive-vector.
