I can only speak for myself. I'm comfortable and sufficiently curious
about this particular flavour of crazy.

I don't think these abstractions are a huge burden as long as the folks
who implement them talk to the relevant maintainers so we don't end
up with Rust inflicted burdens or ill defined abstractions.

Having subsystem maintainer teams supplemented with a Rust wizard, is
probably the best option at the moment. Time will tell as always.
