House locations don't consider entrances/exits or locations within the park. They're selected based on requirements for the design. SS25 was used for Stranger Things because it had to be--it uses nearly every inch of the bigger "one house" soundstage. That left Ghostbusters to SS22 and ONLY SS22. The building was on complete lockdown during construction to attempt keeping it secret.
Klowns was put into Shrek because it didn't need soundstage-level verticality, but DID need enough space to install (and rig) Klownzilla. It wouldn't have fit in a tent because they don't have the same flexibility to hang stuff in them.
So, while I understand your criticisms, there are practical reasons those criticisms aren't considered.
That's not uncommon, actually. They'll plan for/design scares that -
1) They decide just don't work (due to pacing, direction, or design), or
2) They don't fill because they run out of costumes (more common with their custom monster houses).
There are some wrinkles, though. Some of those "booholes" also aren't actual booholes, but rather access doors for Ops. There's also some areas designed to give one performer two (or more) booholes, which obviously means one is empty while the other is occupied. Depending on your timing, it's possible to get bit by neither.
