Is it possible for a transaction that was included in the pending pool across multiple nodes, to become lost from the network forever (i.e. get dropped by all nodes)?
If yes, in what cases is that possible?
P.S. There are a few similar questions but with seemingly conflicting answers. Some say that transactions cannot be dropped from the network (e.g. What happens to transactions in Uncles?), and others say that it is indeed possible for a transaction to get dropped by the network (e.g. What happens to transactions in orphaned/forked blocks?).
