An 'existing' condition in a large townhouse complex (+/- 350 units). The pit is there, the discharge is off to the right, so no trip. Some have Greg's idea of a 'platform', some have fitted covers that are part of the radon remediation, some have...nothing!
As Electure said...stored items can be moved, although it a pain in the butt; and two existing 'wrongs' can be corrected.
