I believe usage of ecryptfs is deprecated for this exact reason. I also filed a bug against it awhile ago back on 17.10.
Keep in mind that almost no system is foolproof against a system admin. If a user wants to protect his data he should use something like KDE's Plasma Vault or Gocryptfs, but they are not automatically mounted like Ecryptfs.
