PHP 7.3 supported?

Was this pulled out because of genuine disuse? Or did some dev look at “BeOS” and say well we don’t need to support a decades dead operating system without realizing that Haiku lives on? Or has build systems become close enough to not have a separately support structure for yet another POSIX system? This seems like a rather big deal for anyone using Haiku for web development. Sounds like this could be resolved a porter recipe.
