Yes. A repair-install would also be a candidate to override settings. The
Lazarus installer doesn't have this option but other could have it.

That is what fpcup is currently doing and iirc codetyphon as well. Problem
is that the format of the XML file is nowhere specified and versions have
changed several times. Current version is "107". I'm not going to repeat all
the arguments you all mentioned against managing settings outside the IDE
and keeping the maintenance to a minimum but these are the same for this
feature request for 3rd party installers. A command line parameter, once
defined, is much more stable than an undocumented XML file. As usual, I'm
willing to make a patch for that provided there is a broad consensus for it.
