We don't have to do this for most controls because the host knows what was last written to each input. And we only save inputs in a preset, right? However, these assumptions make a problem: 1) Writing a preset or saving the plugin state involves writing the value of all the plugin's (input) controls. 2) Controls can be directly connected, needing no host intervention 3) Controls are not readable 2 and 3 lead us to conclude that if the host does not snoop every event, it does not know the value of some controls. So how can it write them out? Either the host has to snoop every event in order to cache every single control change, or controls need to be directly readable somehow. Is it so bad to have a control->get_value() method ?
