It seems important to me to document things present. There is a
section in the docs listing developer-only parameters for runtime
configuration, why not separating "Parameter Key Words" into two
sections then? One for the main parameters and one for developer-only

Because it seems to me that the default value of the parameter should
be an empty string instead of D. Feels more consistent with the
