Logical replication is built with an architecture similar to physical

If so, definitely not the same as having per-database WAL files.
Just as importantly, replication is not, and never will be, a substitute
for backups.
Who says you have to use the mechanism to replicate to another database,
why not to a file?
Not sure of the plausibility, still it might be interesting to find out?
Also isn't a backup just an interrupted form of replication?
