I would suggest either dropping the word "potentially" or removing the
sentence. I'm not a fan of this in-between position on principle even if I
don't understand the full reality of the implementation.

If leaving the word "potentially" is necessary it would be good to point
out where the complexity is documented as a part of that - this header file
probably not the best place to go into detail.
