At the time, the community seemed to have settled on dep - a different, more npm-like way of locking dependencies.
rsc said "nope this doesn't work" and made his own, better version. And there was some wailing and gnashing of teeth, but also a lot of rejoicing.
That makes me a bit sad that rsc is leaving.
On the other hand, I don't really like the recent iterator changes, so maybe it's all good.
Btw if you reading this rsc, thanks a lot for everything, go really changed my life (for the better).
