Is your feature request related to a problem? Please describe.
In Go, envconfig can fail with failed getting user config dir: neither $XDG_CONFIG_HOME nor $HOME are defined, but the docstring says it should be fine if no file exists.
We should verify if this is the case across other SDKs as well and correspondingly fix.
Describe the solution you'd like
We should consider this error to be the same as “no file exists”
