The description of the vector-grid tag says:

Use for questions about vector grids which are also known as fishnets

However there are these questions, which are about the Leaflet plugin for vector tiles L.VectorGrid and not about fishnets:

Adding a popup to features in a leaflet.vectorgrid layer
Using Leaflet.VectorGrid with local GeoJSON and addLayer

Should they have a different tag? E.g. vector-tiles?
