1. Quite a bit, actually. It's really more of a gateway.
2. We could just use lambdas and not have to check in an external UI handler.
Building takes time (and is one common reason some people don't run tests), but
we could build once for most cases as an optimization.

1. Can we actually unit test much by hooking just ::MsiProcessMessage()?
If so, cool.
2. Instead of checking in a binary MSI + external UI handler, we can just
build them.

Subject: [WiX-devs] Making wcautil unit-testable
So I'm looking at fixing http://wixtoolset.org/issues/4668/ (pretty sure I
already identified the issue), but want to make sure we have coverage for the
change which was lacking before.
Many of the Wca* functions call ::MsiProcessMessage via WcaProcessMessage,
which provides a perfect opportunity to use overrides similar to Wiu*, Reg*,
and other APIs. It's been my observation that whatever MsiProcessMessage()
sends goes right back to the external UI handler without modification in most
cases (when not handled exclusively by Windows Installer).
Would we want to provide overrides for unit testing, or maybe just have a small
MSI (though I hate checking in binaries to Git) we can set "install" with an
external UI handler. We could remove the RegisterProduct action to avoid it
ever actually installing.
Thoughts?
