In-spite of all the negative statements on this matter, this exemption maybe the first step in the process of getting this anomaly out of Part 61.
On several occasions we wrote procedures that required exemptions against a Reg or a CAO which were then incorporated into CAOs and then into the re-write of the Regs.
These changes came about because the capabilities of the industry changed and the Regs/CAOs had not kept pace.
There are other examples where exemptions have morphed into the new Regs.
