## Why It's Good For The Game

These are simple machines that are limited by the map spawn amounts and
cargo orders for no good reason. While much more complex machinery can
be built.

Also allows for the construction of pipe scrubber introduced in #84187

## Changelog

🆑
qol: portable scubber, pump and pipe scrubber are buildable as any other
machines
