Share the code for the OOB modern Webparts
Please can you share the code for all the OOB webparts on the github SPFX repo?
Developers can then use these as examples of the methodology and improve upon them. An important factor would be related to presentation as those not familiar with react have to understand how this works.

Thanks for your feedback! Although we appreciate your time and effort to give us this feedback, it’s not something we’re planning to do right now.
We do however review and provide input on the SharePoint PnP / Dev community activities and we do suggest on having a look on the activities and open-source projects on this side. See http://aka.ms/sppnp
We are not right now at least planning to share our code as such but will be using SP PnP as a channel to provide patterns and practices for developer activities.
