This implies that if your plugin depends on property like listen
you can use on output plugin but not on input plugin, host
don't work on both, rather than this custom key like address
work on both.
[OUTPUT]
Name my_output_plugin
Listen something # work
Host # don't work
Address # work
[INPUT]
Name my_input_plugin
Listen something #don't work
Host localhost # don't work
Address # work
