LineageOS is NOT guaranteed to be supported until your phone dies. The Lineage OS devs have repeatedly stated that builds are maintained by volunteers, and if the dev responsible for one phone model loses interest in that job or loses his own phone of that model, he can quit maintaining it at any time, and the community has no right to complain. Because Android development is such an arcane science, usually no one else steps in to pick up an abandoned phone model once the original developer has quit.
