The law doesn't prohibit flying within five miles of an airport without notification, whether it has "gone into effect" or not. It prohibits the FAA from making rules about model airplanes if those planes meet certain requirements, one of which involves notifications to airports.

Sport, there is no requirement in Public Law 112-95 that MA must notify airports.
There IS a protection from FAA regulations for folks that voluntarily choose to meet some conditions.
Seems it does if you don't want them to pass regulations.
?????
We all know the rules/regulations you are talking about will come to be
(cant really say 'pass' since its an arbitrary administration rule/reg and not an elected rep vote to legislate)
Those regs on toy airplanes will come to be,
whether there is Public Law protections for some folks or not.
The only difference is whether the FAA regs
(that have FFA exclusion for CBOAltStandards)
will have protection from congress that will exclude CBO modeling operations from being subject to those regs
(that have FAA exclusion for AltStandards)
