Oh please, in a decade Rust will also be technical debt and people will be wanting to write it in Brust or whatever is the trendy new language.
And the answer to "why now" is quite simple - Because of the whole Rust in kernel debate, people started scrutinizing the situation.
People who become aware of something only when it’s being used by something huge also aren’t early adopters either. Rust has already been in the Windows kernel for years at this point, with none of this consternation.
