Why blame the agency??
Its interesting to observe that CASA is to blame for such "Rules"...I can only hope that the critics of the existing legislation have written many responses for consideration in CASR 91, 61 and 133????
If not then stop crowing foul!!!
FOI's have no authority to allow or disallow variations to existing legislation, and any pilot that asks an FOI of the "intent" of an item of legislation, can be sure that the requester will only get a personal understanding of the legislation....FOI's have no great insight of the rules, however most have read them unlike most pilots.
What you need, and yes your LAME can arrange it, is a Maintenance Approval [MA for short]....its good for life, but renewed every 2 years. [No cost]
Get one, and make your life easy and legal.
