Don't worry. Synapse doesn't often comment on the list of feature requests for Legend/Dune.
Other users have their own favorite feature requests so all you can do is hope that Synapse adds your personal request some day.
I would prefer they not spend one second on Microtuning but Synapse will do what they think is best so who knows what the future holds.
All you can do is make your request, be patient, and enjoy the plugins for what they are today.
