Thanks for the thoughtful comments on project structure and future planning.
I've added some thoughts inline below.

Helping create and maintain is a really important part of the relationship
between SFC and our member projects. Like everyone pointed out the
"bus factor" is an important consideration for governance. Making sure
that there is a robust group of people with varying backgrounds and
skills makes project healthiers.

Also as pointed out, working with contractors is another part of our
bread and butter. Managing funds, both in fundraising and spending,
is one of the core features of having a fiscal sponsor and something
we take very seriously. As noted previously, finding some contractors
to work on security related issues sounds like a high priority task, so
we can help allocate those funds and work with you to find the
appropriate people to get the work done.

I've seen a lot of talk about "open governance" recently, and I think
technical and governance roadmaps are a great place to start!
Once a governance team/ plan has been created, outside people
are much more likely to want to participate since they'll know the
rough structure of the project. It's so hopeful to hear that there are
people interested in volunteering and helping the project out!

I won't speak to any of the technical or infrastructural points about
security, but to say that we leave those choices up to our projects and
support them however they see fit. Also hopefully there are some free
software options in the burgeoning "software supply chain" and artifact
verification spaces, as it's becoming increasingly clear that there are
some open questions in those areas.

Let me know if you have any questions,
