Managing volunteers is hard.
On one side, you need people to do work without paying them. So you shouldn't be choosy and just be grateful to receive help.

On the other side, it is too easy for anyone to simply raise their hand offering to volunteer, but many won't actually end up volunteering/doing the work.

How to figure out who among the people who sign up will actually commit to it?

We need to vet/interview people?

So... adding more work and burden to the community organizers?
