Bloggs:
Whatever they don't have (experience?) that stops them operating in D or C would, I expect, also preclude them from E, given that it is more demanding on the VFR operationally. In D or C, they (us as well) just get told what to do. Easy.
RAA are allowed in E. We are not allowed in C or D, even though it is 'easier', because CASA will not allow RAA to give suitable training. A CTA endorsement was virtually done (after years of lobbying) until Glorious Leader knocked it on the head.

RAAus, why not argue for land rights for gay whales...as much relevance!
If the RAAus was allowed to safely operate in C/D (just like recreational pilots are allowed to do in NZ, the US, the UK, France etc) then perhaps less people would support E everywhere - because E opens up massive amounts of airspace that is unfairly locked to ~10,000 RAAus members at present.
CASA allowed GLIDERS, including motorgliders, in C and D. Why not Jabirus, Tecnams and Cessna Skycatchers?
