I think that's a difficult question to answer because it's hard to do data-access partially. How do you gate that, so it doesn't give everything away for free and incentivizes people to still pay you?
Read-only access might be one way, but I'm unsure how popular that would be.

Generating GraphQL API's for other datasources by funneling them through Postgres
Parent comment is absolutely right that FDW as a general query router is still under heavy development. It's very likely that we'll see further improvement in forthcoming Postgres releases, which will come with additional benefits since FDW are used for a lot more than just "high-level" query routing in Postgres.
I know that EnterpriseDB is heavily invested in FDW development and core Postgres stuff, so maybe we'll see some more neat stuff come out of that team that makes it upstream.
Read-only access might be one way, but I'm unsure how popular that would be.
