Which restrictions do you have in mind?

Quick look at the issue looks like it wanted to avoid using local storage by Prometheus, but that’s Prometheus specific problem, not remote-read problem.

Remote-read is a generic protocol (https://github.com/prometheus/prometheus/blob/a1121efc18ba15...), you pass query (start/end time and matchers), and get back data.

Cortex, Thanos and Mimir all support "remote-read" protocol (documented in Prometheus: https://prometheus.io/docs/prometheus/latest/storage/#remote...), so external systems (eg Prometheus) can read data from them easily.

I believe more like Jæger/Zipkin traces.

Grafana is such a pleasure to work with. I hope all that money won't destroy a nice project.

Congratulations! :)
