See my last reply.

Also, as I mentioned, does this take hours to implement or years to
implement? If it takes hours to implement, the time saved by others
for not confused by finding <= => would surely be worth it. If it
takes years to implement, then it probably should not be implemented
as it is too difficult.

If it takes days (I'd expect that it is what it would take), then it
is up to an implementor's judgment whether he wants to implement it or
not. All that I am saying is that <= => is useful and is probably
surprising to many people that these operators are not available.
These problems are sufficient for the justification of implementing
them.

Nobody forces anybody to do anything. Having justifications do not
mean that there must be somebody forced to implement it. But for the
purpose of justifying so basic operations, I don't think specific
applications are needed.

This can be seen in many languages, for example, javascript below.
Such operators are just implemented without having to provide an
application in the first place.
