adding a +1 to all of the above.
We at Ura Design are already elaborating on a few topics we would like to suggest to support UX Enablement of the OSS community during FOSS Backstage.
As much as we like the idea of a dedicated time and space to exchange and develop among designers, we also see that it somewhat reinforces the thinking that designing is an attachment of OSS, an additional step to take. We strongly believe that the strength of the OSS Community lies in integrating designing into the existing practices. Therefore, we recommend to integrate Design/UX Design into the main event as an integral part.
