PHP 8 compat - no optional param before required

[MegaphoneJon]

Overview

PHP 8 doesn't allow optional params before required params. This param is unused so I removed it

Technical Details

Jenkins won't allow any commits that modify this file until this is fixed.

Comments

I considered simply making it required given that it's only called with FALSE but since it's unused and unlikely to get used any time soon (I don't even understand its intent), I'm just removing it.

Agreed. Could also remove the comment on line 181/179 but is fine as-is.
