The new 121.423 requirement does include recovery from full stall, so as I understand it, this requirement can't be accommodated by current simulators (possibly except Flight Safety's new G550 simulator).
121.423:
(c) Extended envelope training must
include instructor-guided hands on experience
of recovery from full stall and
stick pusher activation, if equipped.
The reason compliance was pushed five years to March 2019 was to allow new Part 60 simulator standards to be published and implemented.
