This is a really cool initative, but I'm a bit worried about spam.

I like this, a long time ago there were quite a few multi-service messaging clients that tied into AIM, MSN, Yahoo etc it was very convenient.

The downside is only the "gatekeepers" have to provide this interoperability, when it would be far more useful if all the popular platforms were facilitating it.

Meta is only rolling this out in Europe. This does nothing to shake their alarming monopolies in places like India.

For the iOS world, ideally the Messages app would be mandated to become a generic interface receptive to protocol plug-ins to interoperate with all messaging networks; and it too itself would be replaceable in that role.
