It may be out of spec for USB C (though I can see someone choosing a
limit of 2A to give headroom on a specified 1.5A limit, AIUI the limits
in USB are on the side drawing the current and there's no requirement
for the supplier to enforce the limit) but that doesn't mean that the
hardware has been designed in a way that makes it safe to just increase
the limit.

What individual components can do here isn't important, what is
important is the constrainst that the system has.
