So... I'm fan of Rust, but while trying to use it one thing was obvious: it
takes _significantly_ longer than C to compile and needs gigabyte a lot of RAM.

Kernel is quite big project, can CI infrastructure handle additional load?

Will developers see significantly longer compile times when Rust is widespread?

Best regards,
