Yeah that could work too.

(However I don't expect that changing it to 1.0 would break everyone.
Only a minority. Because multiple hardware changes are necessary to
trigger a need for reactivacion. In my case, I was changing the MAC
address, upgrading to a 64-bit host (it made Windows see slightly
different CPUID results), and upgrading QEMU (it made Windows see new
hdd/dvd drive firmware versions). All 3 events were necessary to
trigger a need for reactivation.)

Ultimately however I think it should be user-configurable.
