I don't think zig best-practices are written in stone yet, but I would expect ReleaseSafe to be the default in production. Since zig allows turning off/on safety checks on a per-block basis, you only need to pay as much of a performance cost as you want for this.
Actually, this doesn't really come across as a sincere critique of zig. It's more like how a sport fan talks about a rival team (I guess the author must be team Odin). The "first impressions" section is silly.. of course you don't understand how it all works before you've learned anything about it. It might be a bit confusing and have some new patterns. And yes, all the options of the advanced build system is complex, but... you can use the simple build mechanism, or just go with the template for that matter.
Myself, I think there are certainly valid criticisms of zig to make and I don't know if it's ultimately going to amount to something, but you've got to have some knowledge of the subject and not come at it with a predetermined conclusion.
