This is interesting. We recently deployed a solution that uses pmtiles and it's great.

afaik, pmtiles uses mvt, let's hope the tooling to convert the tiles to mlt also becomes available.
PMtiles is often used with MVT tiles, but it can encapsulate a variety of tile types: the current spec [1] has defined tile types for MVT, PNG, JPEG, WebP and AVIF (plus "Unknown/Other").

I'm building PMTiles through Tilemaker, PMTiles is incredible, but sadly it will take a lot of work to produce MLT though Tilemaker :/
PMTiles is actually pretty agnostic to what kind of tiles it contains! There is already a PMTiles PR that updates the byte that specifies the type of tile to include MLT.
