While the replace command will be a powerful way to make changes to a Vault store, it may be difficult to limit replacements in cases where you only want to change a particular key across many paths.

For example, if you have the following Vault structure:

my/vault/path/a:
  first-key: weak-value
  second-key: strong-value
...
my/vault/path/z:
  first-key: strong-value
  second-key: weak-value

And you only want to change first-key's value from weak-value to strong-value, you can't presently do that with the replace command without also changing second-key's value. This is a contrived example, but most of the time, you will indeed want to limit changing values to a particular key.
