The original GPS designers where sending NMEA-0183 data out to devices
that accept and use NMEA data. GPS was not the first to work with
NMEA. Lots of other instruments also output NMEA. I doubt they ever
would have envisioned people using NMEA data for precision timing.
Typically if you want to do precision timing you's use a GPS that
outputs some binary data format. NMEA-0183 does not have flow control
