Clearly if an authority rules that s/e taxi (sic) is only allowed with a dispensation then you cannot do so without one.
In more enlightened regions the authority does not generally interfere with manufacturers guidance on handling technique or general good practice as that is not their job. If s/e taxi does not significantly degrade safety why legislate about it, unless you're feeling under-employed or needing a power-kick?
Jeez, they'll be telling us which auto brake setting to use next!
