The premise
Deprecation cleanups stall because finding all callers and updating each correctly takes scarce attention; AI can do the discovery and draft per-call-site patches.
What AI does well here
- Find call sites including dynamic and string-based ones
- Propose minimal replacement code per site
- Group sites by replacement pattern
- Draft a single PR description summarizing the sweep
What AI cannot do
- Detect call sites built from runtime metaprogramming
- Know which call sites are actually dead code
- Verify that the new API behaves identically in your environment
