There's a strong culture of "leave things better than you found them". When a user gets confused by the tooling/language, it's not the user's fault. If you got confused, chances are that others will too, so fixing/improving things when we encounter them has unbounded benefit. Second best time to plant a tree being today and all that.

One benefit of this is that if someone tries and bounces, when they try again a year later their experience might be improved enough that they don't bounce again. For a while I was of the thought that the best piece of advice I could give someone wanting to learn Rust was "wait 6 months" :)
