I think by "ENR 1.1 10..." you mean "ENR 1.10 1..."
I'll take the deep dive...
Correct.
Incorrect.
My logic (!): Part 91 Plain Engliiis section 10 (page 70). By omission, you are not an IFR flight so the IAP/TAF requirements don't apply. If it doesn't say you can't, then you can!
ENR 1.10 section 1.2.1 doesn't make sense, both because it contradicts the new rules, and second, it contradicts itself:
Forecast information must include a. an aerodrome forecast...
then at the bottom:
...the minimum requirement is a GAF.
AIP ENR 1.1 10.7.1.3 contradicts the new rules as well.
Ref the VFRG page 80:
You
could say the GAF is your forecast for the destination (which, according to the Part 91 bits, it appears to be [for VFR]), so you don't need to nominate an alternate.
But then, in the next section "Destination alternate not required", the VFRG omits your scenario, where you're going longer than 50nm in good weather. Now if it had said "Destination alternate required when", then it could be made to read better.
Correct.
