We didnât harvest anything. I think itâs reasonable for GNU maintainers get in touch one another, and thatâs unfortunately the only to do that reliably AFAIK.
No, the accepted method is the internal lists. You are under no right to use the private information of GNU maintainers. Itâs about building a shared understanding of what it is weâre aiming for as a project. To me, that can only be beneficial to the project and its cohesion. Feel free to join in the already ongoing conversations then, your efforts are not part of the GNU project though.
