Something like
$data = compile_time_routine(function() {
return json_decode(file_get_contents("large.json"), true);
});
being equivalent at runtime to
$data = array(...whatever json_decode returned...);
and
echo "opcache compiled at " . compile_time_routine(function(){return
date(DateTime::RFC3339);});
being equivalent at runtime to
echo "opcache compiled at " . "2023-03-16T09:43:00+01:00";
- at my work there are jsons which is being fetched/parsed like
$data=json_decode(file_get_contents("large.json"), true);
several times per second, while it would be fine for them to only be
fetched/parsed every time opcache is reset.

You can already sort of do this by having a build script that reads the JSON file and then uses var_export() to dump it to a file. You can then just require the file to get the resulting array.
Not precisely the same, but gets the same benefit in this case.
