Does Jolla intend that the Sailfish platform should be OpenGL ES 3.0 compliant, in order that app developers can have surety that in targetting new API's they don't disqualify a large proportion of the potential audience?

Even if OpenGL ES 3.0 support doesn't arrive in v1.0 of Sailfish, at least ensure the hardware is compliant:
