In this article (bit.ly/2zLX8MZ) about bike fit, the author supports that

When you fit a bike perfectly there is
no need for headset spacers.
What is your opinion?
Yes. No need at all for spacers. Don't even think about either getting out of the condition at which you were fitted or improving it. Don't get sick. Don't crash. If you want to ride longer rides or shorter faster ones, get some more bikes and set them up right. Don't age. (And after that fitting, mark your seatpost with tape, clean it and the seat tube up with solvent, grease with epoxy and reinsert. Wouldn't want that ever changing.)
