One clear advantage of the new SVG format is, apparently, that Arabic script is now, finally!, rendered the way it was always intended—left-to-right with unconnected letters /s

There is still no good library which takes in a MVT tile and spits out the appropriate PNG or JPEG for rendering in via a tile base mapping engine. There is still no good cross platform mapping engine that can render vector tiles in a way that is easy to consume. There are certainly engines on specific platforms, but unless we use something like Leaflet or OpenLayers it is hard to make it work with native APIs on, say Windows, MacOs, Linux, iOS or Android without needing to adding a whole browser engine on top of your app.
This link is shrinking though! There's slowly growing support. Leaflet and OpenLayers are fundamentally limited by being canvas-based, so there's only so much they can do.
QGIS has one of the fastest, cleanest MVT renderers I've seen, but I don't know how easy that would be to extract out.
PostGIS is the best platform for generating vector tiles, but it's extremely clunky. On the projects I'm working on (eg https://vectorcharts.com/) I do extensive processing in PostGIS, but then encode to vector tiles in bespoke C++ code.
