editions

My reading of this was that they wanted to set a *maximum* edition on Rust code that could go in the base - so that developers could target 2024 and anything older, but not 2027 (until they updated the requirements).

I suspect a minimum supported version would work better, given the way features stabilise in Rust currently - the only advantage of specifying an edition I can think of is that it might make it easier to integrate with other implementations like gcc-rs . . . though I guess we won't really know how that might work until we have actual practically useful alternative implementations.
