Generally I don't think there should be a central catch-all variable for
this, ebuilds should use their own unlikely variable as needed if using
this route until a better solution.

e.g. MARIADB_I_ALLOW_THE_DESTRUCTION_OF_MY_DATABASE=yes

Could take it further and require that =yes be =${PV} so that it only
works once if forgotten.

Then users setting this in not-so-great ways are still unlikely to be
bitten by it.
