may be but it does constraint the possible heuristics used for

Maybe it would be enough to mention that the heuristics for establishing
shim sessions also are used for recover from those situations where the
context has been lost. However, i guess that need to take into account
where the heuristics for establsihing shim sessions are not useful for
recovering from lost state and provide a worst case recovery for this case.
Yes, it makes sense to describe this part of state recovery, and any
implications it has on the recommendations for the heuristics used to
determine when to establish shim state.
so, so far what we have is:
- before a rehoming event, packets may not be identified as belonging to
a shim session. If this is the case, the data packets associated to this
sessions are not useful to detect context loss, so alternative
mechanims, like using the heuristics for establishing shim sessions are
used for recover from this situations
- after a rehoming event, context loss is detected upon the reception of
any packet associated with the shim session, whether signalling packet
or data packet. for that, data packets need to carry at least one bit
that identifies them as belonging to a shim session.
Makes sense to me.
