Hi Magnus,
2) Timing versions might get an upgraded oscillator. Maybe a TCXO
instead
of a standard XO.
Don't think so. The noise and systematic stability is as important for
positional as for timing versions, the timing version can benefit of the
fixed position.
Look at the uBlox6 lineup. Position receivers are available with XO or
TCXO - timing only with TCXO.

In that case they are the first to do it to my knowledge.
None of the Motorola receivers did it as I recall it. Could be that the
price of the modules is now so low that the difference make sense.
Notice that producing higher navigational rate is easy if you have the
CPU power to do it, and todays receivers have higher CPU power than they
used to, so doing 10 Hz navigation rate isn't unfeasable, so it does not
need to be Kalman filter predictor results.
Cheers,
Magnus
