If that is me you are referring to das uber, I can see how it could have come across that way but it was not my intention.
1.2.1 seems to answer the question about if an area forecast is acceptable or not, very clearly, I thought, so I didn't elaborate.
1.2.2 and 1.2.3 also spell out the other questions raised by others fairly clearly as well, in my opinion.
Agree that the rules are written in a very grey manner. Reading 1.1 57.1.3 in isolation certainly gives the wrong idea. Very common with the casa regs - ban everything and then tuck away explanations/exceptions elsewhere, and ban a few extra things elsewhere while you're at it, with no particular logic or structure. Just look at the number of rules that apply to all flight that appear under the title of air operations, a term that implies commercial operations.
