Are there already plans or other developments in this direction?
As ODC includes already a web service (https://github.com/opendatacube/datacube-ows) supporting the classical OGC web services (OWS), I think there should be a broader interest in also supporting the new API suite.
A new suite of OGC API standards is being developed and coming more and more into practice (https://ogcapi.ogc.org/). pygeoapi (https://pygeoapi.io/) implements already several of these new APIs. We recently started to implement a provider plugin for pygeoapi to support ODC as a data resource (https://github.com/MartinPontius/pygeoapi-odc-provider).
