The INI list is not meant to function as a sitemap, it is meant to provide an exhaustive list of options, but does not necessarily have to link to manual pages foreach option.

It is sufficient that the options are listed somewhere, regrettable as it is, some extensions have options that the authors do not want to expose to every user, so they choose to document it partly or not at all.

While we might have experience with some extensions, the documentation team do not have enough experience with every extension to make calls on what should and should not be included, or more specifically where it should be included.

We do try to keep ini.list complete and relevant, but the configuration section for any one extension, is not required to be exhaustive, and may leave out options for the users own benefit. There are no general rules that we can apply.
