vector tiles are years-old now.. there are a dozen decent implementations.. why would Leaflet not support vector tiles ? is there some commercial agreement behind closed doors regarding crippled Leaflet now?
Things that are mandatory for map display, like:
- Label priority and positioning
- Display of internationalized, RTL, and Bidi text
- Geometry rasterization and styling
Are outside the scope of Leaflet's core design and can be implemented by plugins, one of which I have linked in a sibling comment.
