Honestly, I've been pretty disappointed with HashiStack for a while. It always seemed like they didn't really take any minor contributions unless requested from a customer (i've been waiting for terraform to support a 2-3 year old vault PKI keys for a while). They also dark patterned their website recently to make download links and documentation hard to find.

I've seen one quote when we wanted to buy Vault Enterprise for peace of mind (we did not need namespaces), and well, it was completely out of reach. Moon prices. No wonder people turn to someone else hosting these products for them.
