Hi,
this sounds all reasonable to me, and as mostly a lurker on this list my
input shouldn't carry too much weight anyway.
I wanted to point out one thing: Docker does continue to offer free
access for Open Source projects, it's just that they restructured the
way of how to do this. So if there is still value in Docker, an
application to the Docker-Sponsored Open Source tier should certainly
fit Numpy. A bit more information is at

Thanks for the suggestion Klaus. It doesn't really fit us. I've spoken to multiple maintainers of other projects who went through this application process. It's very bureaucratic, may take months, and is only meant for projects with needs a lot higher than hours (as determined by an actual interview apparently). On Twitter I've seen similar sentiments from maintainers. So I'm pretty sure it's not worth applying for that.
Cheers,
Ralf
