I donât think there is any call for setup.exe to be highly backwards-compatible.  It isnât asked to deal with old package repos, very old versions of setup.ini, etc.  Therefore, I would say that whoever is in charge of this code base should simply get rid of the bitrotted features.  

If any of these obsolete features are needed again in the future, they can be pulled out of the SCM history.

Okay, but...

Replacing core infrastructure like this almost never works out smoothly, and usually fails outright.  Itâs far better to remediate the code base in-place, if at all possible.

There have been a bunch of attempts in the past at replacing setup.exe. At least 3, that I can think of.  All have fizzled.
