Nim is really active as well and IMO better for app devel (while rust takes
it for a C replacement for system devel).

Yes but you could get this too as an SQL dump or via some other
translation.  Wouldn't have the problems the current parser has where
you can't safely add things.

Well all talk of rewrites goes in that category.  But if I did it, I
would use the
JS backend and webgl.  All the hard work on the renderer is already done.
It's not actually all that far-fetched, the only sad part I see is you
would need
round-trips to the server to get sql rtree and transactions for undo,
so it would
be unusable over slow connections.  But it would be free so you could just
run server locally instead :)
