Under the new policy a number of old machine types (any prior to 2.12) would be liable for immediate deletion which would be a violation of our historical deprecation and removal policy Thus automatic deletions (by skipping QOM registration) are temporarily gated on existance of the env variable "QEMU_DELETE_MACHINES" / QEMU version number >=3D 10.1.0. This allows opt-in testing of the automatic deletion logic, while activating it fully in QEMU >=3D 10.1.0. This whole commit should be reverted in the 10.1.0 dev cycle or shortly thereafter.
