Yes, map reform is absolutely on the list, and something that has been discussed a lot internally. We have some really nice features of our map (the choices of which orders to display are good, the province colouring is nice), but we also have some rough features too - the map is really pixelated, sometimes it can be hard to tell which unit is which type (Bulgaria is a particularly nasty culprit here), it's not clear to (some) new users what country the units belong to, etc.
My preference is for an SVG map with coloured stars and anchors for the units, provinces coloured, and a stack of other small changes we've been looking at.
The problem with the map (and other webdip features and improvements) isn't ideas - it's time. We only have a limited amount of time to work on features. A couple of times over the last couple of years different people have offered to add SVG map support, but it's never come to anything.
The vDip classic map is actually slightly different - I think it ensures that province text never obscures the unit, which is an improvement.
Keep in mind that we have a stack of map features already implemented - when changing the map, we'd need to redo preview, ensure that it works with the colourblindness tools, etc etc.
