I completely agree with your medical analogy, Brock. Establishing a 
known-good baseline is fundamental to system triage.

However, you are misinterpreting my concern as a novice's confusion over 
normal anatomy. Having actively investigated malware and system 
anomalies since 2005, I am well aware of what a healthy macOS baseline 
looks like, and I fully understand that legitimate applications utilize 
background services, LaunchDaemons, and privileged helpers for low-level 
tasks.

My concern is not with the existence of these tools; it is with poor 
digital hygiene and "orphaned" persistence.

When a developer uses the SMJobBless API to install a helper tool with 
root privileges, but provides no mechanism to clean it up when the user 
drags the main application to the Trash, they leave a persistent, 
root-owned binary sitting silently in a system directory.

In the security world, we look at attack surfaces. An orphaned helper 
tool left behind by a deleted application is an unnecessary liability. 
If that helper tool has any undiscovered vulnerabilities or loose 
permissions, it can be subverted by local malware for privilege 
escalation. Furthermore, hidden, un-monitored system folders are the 
exact real estate malware authors look for to achieve stealth persistence.

The issue isn't that legitimate software is malicious. The issue is that 
lazy uninstallation methods leave the door unlatched, making the 
system's "normal anatomy" harder to defend.

David
