Sort of. The point of Vault is you're supposed to actually use RBAC and least privilege and store NPE credentials that are properly scoped to the actions you're comfortable automating, which your NPE then gets a certificate to fetch on demand, rather than just giving it your own personal root credentials that can do anything.

We're going to see this reinvented thousands of times in the next few months by people whose understanding of security is far poorer than HashiCorp's, via implementations that are nowhere near as well-tested, if tested at all.
