SMPTE is two things (at least):

SMPTE cannot specify fractional frames because such things are not part
of the format (my understanding of this is based more on MTC, so
perhaps I need to say that MTC cannot encode fractional frames).
not for locating to a given position. i know you
can interpolate
running SMPTE, but when you use SMPTE as a point in time to go to,
this option is not available. you therefore can't use SMPTE to specify
sample-accurate edit points, etc.
I really don't see the problem.
IF every cycle is timestamped, then so is every sample. Say you wand to drop-in at time t. Start playback,
wrong scenario. suppose i want to store the point in time where (say)
a zero crossing happens. SMPTE will not allow me to do that. i have to
store it as a sample position. if i use SMPTE, then i am not
guaranteed that the result actually refers to the desired sample.
