I was assured all would be fine if patched properly. Got this from one tire manufacturer:
"If all of the following below was completed by a competent tire professional, then the repair should be fine for the life of the tread.
The tire was thoroughly inspected prior to the repair, with the tire showing no signs of run low or run flat.
The puncture was ¼” diameter or smaller and in or near the center area of the tread.
The tire was properly repaired using a plug patch combination
Please note that the Tire should now be de-rated by one speed rating. So if you have a “W” (168 mph) speed rated tire- it should now be considered a “V” (149 mph). This maximum would be for the vehicle, even if the other three tires had the W rating or higher."
