2 and 255 in this example

   std::counting_semaphore<255> sem(2);

follow pretty much the same semantics and serve pretty much the same 
purpose as 2 and 255 in the following example

   std::uint_least8_t n = 2;

(Even though the latter does not mention 255 explicitly, I hope you'll 
figure out where it hides.)

Whether you will ever "use" it or not is a different question.
