Multitenancy: is a Proxy PDB part of the 3 free PDBs at 19c

Multitenancy: is a Proxy PDB part of the 3 free PDBs at 19c

As most of us know, Oracle Database 19c now supports up to 3 pluggable databases (PDBs) per container database (CDB) without requiring additional multitenant license—applicable for both Standard Edition (SE2) and Enterprise Edition (EE). This documentation clearly states: “For all offerings, if you are not licensed for Oracle Multitenant, then you may have up to 3 user-created PDBs in a given container database at any time.” Meaning it’s about user-created PDBS.

But is a Proxy PDB (in fact a kind of symbolic link in Linux terms) considered user-created, or are you allowed to have 4 PDBs in theory? Once, I attended a presentation of Carajandb (Johannes Ahrends) in Germany, who stated that a Proxy PDB is free to use, based on the 18c documentation.
