 > > On PHP < 8.1, I suppose the reason to add this alias is to keep
 consistent with other code, right?

 > Because some theme, plugin or site specific code in the wild might use
 the (old) function when running PHP 5.6 - 8.0, it's needed not to cause a
 fatal error. We can't expect those devs to write PHP 8.1 compatible code
 in many, many years.
