Lately, it seems like most issues aren't even being acknowledged. It's pretty frustrating to encounter a bug in a documented use case, spend hours trying to fix it, realize it's a Next issue that was filed months ago but has yet to receive a response from Vercel, or to have reproduced and explained the issue and be ignored for months and counting.
The issue count at Next is huge, and I'm sure overwhelming, but if you're going to hype "stable" features that are beta at best, there ought to be some measure of support (or at least acknowledgment) for when they don't work.
People invest their livelihoods in these frameworks, and false claims are damaging. I'm currently knee deep in a project that can't budget a rewrite, so I'm just hoping someone at some point notices these issues and they get fixed. Not great. I've yet to encounter a project that calls features "stable" as carelessly as Next does. I've never felt so burned by open-source marketing.
If I was starting a new project today, I would stay away from Next.
