The number would need to be parsed twice: first in the json parser, to
check it is a valid number, secondly in the handler, to give an actual
number. Given that some json parsing libraries implements their own
number parsing to avoid this double parsing, constructing the value on
the fly, i’m not alone in thinking it makes a difference (from what i've
seen, boost::json authors also are on that boat, which makes their
interface choice a logical one).
