And if you use it for anything beyond office/Web surfing, you configure the system for a few days afterwards... (Except if you have a professional setup with some configuration management behind it, which the target group of this proposal most probably doesn't have.)

OK, that shows that you are not a professional. This is bullshit, plain and simple: For private and SOHO users, WGA may trigger reactivation, but no reinstall. (Enterprise-class users use deployment tools anyhow and do not come in such a situation.)
