a triager would be very welcome; someone that can ask follow-up questions on issues, create test cases for the problems, and so on.

Show me good PRs, bug triaging, documentation fixes, whatever and you're a candidate if you ask for it.

I agree, it would be great to join forces and speed up development... Svelte really needs one safe material library option.

Maybe @hperrin would be able to make an appearance and select a few additional maintainers to help out.
