Comment (by swissspidy):

 @jrf Will do!

 @costdev Thanks for raising this.

 Happy to add the tests for sure.

 Looking at https://3v4l.org/tgUEX/perf and https://3v4l.org/MLs3Z/perf for
 the relevant version range (PHP 7.0 to PHP 8.0), user time is identical.
 Maybe the performance inconsistencies were a thing before WP bumped its
 minimum requirement? It does look like implementing both approaches à la
 Symfony is redundant, so it makes sense to just settle on one (assuming
 the tests confirm that)
