Have you noticed any issues/differences compared to Vault? We ended up moving completely away from Vault because we didn't use most of its features and it wasn't worth the cost.
I was going to migrate my homelab from vault oss -> openbao, but I'm debating on whether that's even worth it or just going back to gpg encrypted files or something.
If you're going to expose static secrets to your app, it kind of doesn't matter whether they are in a single vault or in a gpg encrypted file or something. The real benefit of a vault IMHO is to distribute dynamic certificates instead of a static secret, so that way it's time-boxed, and the static secret (private key) never actually leaves the vault.
