# the path from /_matrix/client/unstable/account_validity/... to
# /_synapse/client/account_validity, because:
#
# * the feature isn't part of the Matrix spec thus shouldn't live under /_matrix
# * the way we register servlets means that modules can't register resources
# under /_matrix/client
#
# We need to allow for a transition period between the old and new endpoints
# in order to allow for clients to update (and for emails to be processed).
#
# Once the email-account-validity module is loaded, it will take control of account
# validity by moving the rows from our `account_validity` table into its own table.
#
# Therefore, we need to allow modules (in practice just the one implementing the
# email-based account validity) to temporarily hook into the legacy endpoints so we
# can route the traffic coming into the old endpoints into the module, which is
# why we have the following three temporary hooks.
