thinning AVGAS infrastructure at unmanned ghost towns.
That's a symptom, not a cause.
The regulator - CASA, not Airservices - position was that the introduction of issuing NOTAMs re fuel could lead to the interpretation of no NOTAM = fuel available, which may not be the case, and that instead NOTAMs should not normally be issued and the practice of pilots telephoning to ascertain fuel availability should continue.
That will be Airservices position too. The GLA NOTAM is an aberration.
