The conversation around Nim for the past 20 years has been rather fragmented - IRC channels, Discord channels (dozens, I think), later the Forum, Github issue threads, pull request comment threads, RFCs, etc. Araq has a tendency to defend his ideas in one venue (sometimes quite cogently) and leave it to questioners to dig up where those trade-off conversations might be. I've disliked the fractured nature of the conversation for the 10 years I've known about it, but assigned it to a kind of "kids these days, whachagonnado" status. Many conversations (and life!) are just like that - you kind of have to "meet people where they are".

Anyway, this topic of "error handling scoping/locality" may be the single most cross-cutting topic across CPUs, PLangs, Databases, and operating systems (I would bin Numpy/R under Plangs+Databases as they are kind of "data languages"). Consequently, opinions can be very strong (often having this sense of "Everything hinges on this!") in all directions, but rarely take a "complete" view.

If you are interested in "fundamental, not just popularity" discussions, and it sounds like you are, I feel like the database community discussions are probably the most "refined/complete" in terms of trade-offs, but that could simply be my personal exposure, and DB people tend to ignore CPU SIMD because it's such a "recent" innovation (hahaha, Seymore Cray was doing it in the 1980s for the Cray-3 Vector SuperComputer). Anyway, just trying to help. That link to the DB Null page I gave is probably a good starting point.
