Fixing the redirect chain won't affect the change history or integrity for a specific profile, and redirect cleanup (short circuiting the redirect chain) would keep the end result the same and make google happy. It actually makes things simpler rather than more complex (fewer steps in the redirect chain, same final profile). This doesn't change any of the existing guidance about needing to merge into the lowest # or minimizing redirects, it just helps when people may miss that lowest number (happens often, especially when merging entire trees, or reconciling different LNAB). Perhaps you could start with the simplest cases (no change in LNAB with multiple redirects, with a very long chain). Anyway, sounds like you've already looked into this particular solution, thanks for the clarification.
