If you want to avoid both the surprise and confusion factor mentioned
before, maybe what's needed is to *remove* --analyze-in-stages, and replace
it with --analyze-missing-in-stages and --analyze-all-in-stages (with the
clear warning about what --analyze-all-in-stages can do to your system if
you already have statistics).

That goes with the "immediate breakage that you see right away is better
than silently doing the unexpected where you might not notice the problem
until much later".

That might trade some of that surprise and confusion for annoyance instead,
but going forward that might be a clearer path?
