FireGiant contributed BOOTSTRAPPER_REQUEST_STATE_MEND to v4 in
https://github.com/wixtoolset/burn/pull/51. It vaguely reminded me of
someone asking for control over REINSTALLMODE in bundles - #5911. MEND
seems to me to be a v3-style targeted fix for the more general feature
requested there. So my question while we can still make breaking changes is
- what's the relationship between these? Also, it seems odd to me that MEND
doesn't have an overall BOOTSTRAPPER_ACTION and must be requested
per-package. Some background on what MEND what was built for would be nice.
