I would prefer 1), because 1/octave might be useful for modulation, but 
just complicates matters if the task at hand is setting an oscillator to 
a specific frequency.

One could even argue that oscillators should not have 1/octave ports at 
all, but that there should be a plugin that takes a 1/octave modulation 
input, a Hz base input and delivers a resulting Hz output. The DRY 
principal applied to plugins.

Even for modulation, a plugin/infrastructure that allows the user to map 
any value range to a frequency modulation range in semitones could be 
far friendlier and does not necessarily need 1/octave behind the scenes.

I doubt consistency with the original plugins will matter in practice at 
all. The added workload for you sucks, of course and only you can weight 
that aspect of it, David.
