From the outside looking in, it seems that despite trends in language development to the contrary, Rust has taken an extremely conservative stance on the inclusions into and the evolution of its standard library. I applaud the decision and the will of the core teams for sticking to their guns in this area. I had assumed that the reasons you give above were the motivating factors for being vigilant about the slower cadence of development and smaller ‘size’ of additions/alterations/removals to the standard library . But having it confirmed makes it very comfortable for me to think it is a nearly unqualified positive stance for the language to take.

I have seen your talk about the long future of Rust and I think there is the implication that you and the other Rust language developers are looking toward a 25-30 year timeframe (which encompasses nearly every language in wide spread use today) as the minimum expected lifespan of the language, with a view to be responsive and flexible enough to see the language continue to adapt and evolve throughout a longer period as well. With that type of longevity as an active consideration in planning the language’s growth/evolution I think Rust is setting a good precedent for non-BDFL style governance and stewardship of programming languages. I would hope a more long term compatible view takes hold in programming language development particularly, but general software development could probably stand to benefit if the time horizon was lengthened well beyond what seems to be standard today.
