Re-consider per vertex TTL

One of the key questions raised in the discussion is what happens if a vertex/edge/property with TTL is updated. Some may not want the update to have any impact on TTL, others, like myself, would like for the TTL to be extended. One particular use-case where an update triggers a reset of TTL is in the area of session management.

Curious what happened to this. There was an experimental build that implemented some of these features. Was this deemed not necessary or did we just get sidetracked and not get back to this ? Is there final agreement on the overall design ?
