Unfortunately I don't understand much of that preamble. If you're
getting failures during upgrades, perhaps explain how reboots are
involved, if that's what you're looking at. I've only heard the term
"hardening" in the sense of "making a system more resistant to cyber
attack" (look it up!) so maybe you mean "more reliable", and if so the
answer to that is a good install design that follows best practices.
Perhaps you could explain why doing a reboot in the worst case is a
good thing, because it's usually not. I've never seen anyone
successfully outwit Windows in dealing with reboots during an
installation because it knows much more than you do about what's going
on, and by "dealing with" I mean minimizing to reduce the impact to
the customer.

The docs are clear about MsiSystemRebootPending. Use it in a launch
condition, and especially when a previous install has finished that
needs to be really complete, with files updated instead of pending a
change. It's nothing to do with your install  - it's about the state
of the system.

ReplacedInUseFiles is set when your install has replaced in use files,
obviously, but if a reboot is required Windows will do it anyway, and
you don't need to schedule a reboot because ReplacedInUseFiles is set.

There are no cases AT ALL that I know of where YOU need to schedule a
reboot. Windows will do the right thing if you let it. Again, if you
had issues associated with reboots you could tell us what they were. I
have known people who've built installs that were so honked up with
things like custom actions and badly written services and other
processes that refused to shut down when told, and rather than fix
those they forced a reboot on the customers - hopefully that's not
your situation.

Look at the msiexec exit codes. If you are running bat files or the
equivalent and you have anyone that can code, write something that
calls the Win32 API MsiInstallProduct. When it returns 3010 it means a
reboot was required but it was suppressed by (usually) a command line
that said suppress reboots (see REBOOT property), same with the
msiexec exit code.
