This is becoming silly,but lets bite..
Standard thrust reduction (A/B/1/2) dont start before 800 AAL,i guess you know that.
Windshear,you mean convective? or gusts?
Convective windshear a no go obviously.
If you suspect or are reported gust windshear or turbulence,thrust reduction and acceleration would be initiated as normal(acceleration not below minim acc height) and full thrust would be used.
If you encounter turbulence,tighten your harness bit more.
If the turbulence happens to be severe and you decide to accelerate below the engine min acc height and below the noise level altitude,(reduce load factor on your flaps and pax)then i think it is OK because you are now dealing with a situation that requires an acceleration rather than a theorytical engine failure.

If you actually encounter windshear,(windshear alert on your ND)apply the windshear recovery procedure which is to disconnect the AT and maintain your config,flaps...
If you get out of it and start accelerating(retracting flaps) and it is below the noise acceleration point then it is not a problem.

But if you think i will plan to accelerate at 400ft(lets say it is the minimum) and reduce thrust at (800 ft minimum by std noise) just because there is turbulence or windshear reported,the answer is NO.

This what you posted pilot737 and what i dont agree with and flying into airports like chambery or Innsbruck you may understand..
