For backwards compatibility, we would also preserve the existing convention of doubling up the resolution operator as an escape sequence. So, for example, both of the following would be supported and would produce a Label instance with text "$foo":

Is it really necessary to support the old format? The more extra cases
you make the harder you make it for tooling vendors because they have to
support 2 formats.

I would vote to only support the new version and documenting in a
migration guide that $$ is not supported any more but that's just me.
