The straight WiX toolset should never require anything more than MSI v1. However, the Windows Installer really isn't "good" until MSI v3.1 and much functionality doesn't work well until you have MSI v3.1. MSI v4.5 isn't well distributed so we only take advantage of features there opportunistically.
If we find a hard dependency on MSI v4.5, that typically was a mistake and we need to fix the code to run on MSI v3.1.
