Feel free to write an adaptive grid 3d plotting routine. It would be a 
great thing to have, but this is not what  #12798 is about.

I disagree. It is in the IEEE standard, and you ought  be allowed to pass 
any floating point value to the 3d plotting code. OpenGL states that the 
result is undefined (i.e. may lead to graphics glitches), but that it must 
not lead to GL interruption or termination. So it might not be the most 
beautiful result, but it ought to be harmless.
