My only gripe is that the tile metadata is stored as JSON, which I get is for compatibility reasons with existing software, but for e.g. a simple C program to implement the full spec you need to ship a JSON parser on top of the PMTiles parser itself.

A JSON parser is less than a thousand lines of code.

And where most of CPU time will be wasted in, if you care about profiling/improving responsiveness.

How would you store it?
