Yeah, agreed.  Though the new in-tree one could be renamed to tsx-mode.
That will support both typescript and tsx, anyways.  Or it could be made
to not work on 29.1, hehe.  I don't really have a strong opinion, but
seeing the state of the current typescript-mode, I do think there's a
case here for actually superseding it.  But that's not really my call to
be made. 

_I_ think the best name here is typescript-mode, but it could be
tsx-mode, typescript-tree-sitter-mode or anything else.

How about deprecating typescript.el the moment the 29.1 branch is cut?
After we can but some sort of structure in place for the two to coexist?
