Can somebody from LE explain why "Rust in the kernel" is a story for LE, rather than for Linux itself? Did LE e.g. do the coding? or help? is this a cross-product activity? LE is a system for bootstrapping CA certification, Rust in the kernel is a generalized memory/systems security & safety coding activity.
Not that it isn't good, but "why talk about it in a letsencrypt end of year message" -is this the wider "we" at play, or was there something specific I missed?
