It's especially a red-flag since an enormous number of projects (almost all of them?) will never tolerate shipping fat binaries (ie what cosmopolitan C is in reality).
The core of this a library called nsync. It appears most of the improvements by Justine are upstreamed into nsync itself which doesn't have any of the baggage of cosmopolitan. Whatever your opinion of the project or author, they've made good effort to not lock you in.
Agreed; this is what I've always (silently) thought of those fat binaries. Absolute stroke of genius, no doubt, and also a total abomination (IMO) from a sustainability perspective.
