Sure, we could add -O or another runtime enabler,
or could force UpgradeTVDatabaseSchema() and friends to alert the user?


From memory, I think the original intent of the IGNORE_ hack
was to allow _quick_  build/run/debug against a mismatched DB.
I think the automatic DB backup stuff was added just after this,
to make the “weapon” less dangerous.
