deprecated.html says:

pc-i440fx-1.4 up to pc-i440fx-1.7 (since 7.0)
^^^ ^^^
These old machine types are quite neglected nowadays and thus might have
various pitfalls with regards to live migration. Use a newer machine type
instead.

Unless the qemu documentation is severely misleading, that does not
include pc-i440fx-{2-8}.{0-12}, and there is no indication that the
machine type "pc" (current alias of pc-i440fx-8.1) has been deprecated.
