For Postfix 3.2 I'll update code and documentation, such that the default option_group value becomes "client". This causes the "client" option group to be read twice instead of never (reading it once is not an option). To get backwards compatibility, specify an empty option_group value.
For the stable releases I'll update their documentation with a
suggestion to specify "option_group = client". An incompatible
code change would be forbidden.
