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?
Because Leaflet is an extensible library for building map UIs using the browser, using DOM elements as grid cells, and using SVG in some cases for overlay geometry and user interaction.
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.
