To be honest, I think I'll probably move all of this stuff (including the original uk_gsps) out of a SQL file and into a CSV or parquet in the client repo. This can then be applied with a simple python script calling the API (that way it's agnostic to database changes and only affected by breaking changes to the API contract). It doesn't really make sense to bundle any of it with the data platform, as it isn't part of the migrations (and that way I can add the UKPN stuff to it as well). So I'll take these names you've defined here and put them in to that set of data.

That make sense, free free to close
