- FreeBSD has no default LLVM version downstream atm but folks try to reap old unused. - OpenBSD has only one, unfortunately, affected by bug 1357889. - Bug 1356991 is unclear whether the new default would be limited to automation (a la --enable-rust days before 53.0) or for every build on mozilla-central. $ ./mach bootstrap [...] Stylo is an experimental rewrite of the Gecko style system in Rust to be faster and make better use of modern computer hardware. Would you like to download packages for working on Stylo? If you're not sure, select "No". 1. Yes 2.

Is that trust justified?

Is that trust justified? No, it assumes with enough dogfooding Stylo would build against future LLVM releases (e.g., 5.0.0 or even 4.0.1). Let's drop OpenBSD bits for now.

Llvm is already installed by https://dxr.mozilla.org/mozilla-central/source/python/mozboot/mozboot/openbsd.py#25 anyway.
