I don't see it on macOS 10.15.4 (19E287). The full list of categories on my Privacy tab:

  - Contacts
  - Calendars
  - Reminders
  - Photos
  - Camera
  - Microphone
  - Speech Recognition
  - Accessibility
  - Input Monitoring
  - Full Disk Access
  - Files and Folders

  - Analytics & Improvements
Granted I don't typically use Terminal.app (iTerm 2 user), so I launched terminal and did some privileged stuff. Had to grant Full Disk Access to, say, `ls ~/Library/Mail`, but "Developer Tools" never popped up.
Are you running a beta build or something?

Update: Okay, I checked on my other machine and that one does have it (Terminal is listed but disabled by default). What in the actual fuck?!?
