I don't entirely subscribe to the first paragraph – I've never worked at a place so dear to me that spurred me to spend time thinking about its architecture (beyond the usual rants). Other than that, spot on

Yup, this is part of what’s lead me to advocate for SRP (the single responsibility principle).

Even that gets overused and abused. My big problem with it is what is a single responsibility. It is poorly defined and leads to people thinking that the smallest possible thing is one responsibility. But when people think like that they create thousands of one to three line functions which just ends up losing the what the program is trying to do. Following logic through deeply nested function calls IMO is just as bad if not worst than having everything in a single function.

There is a nice middle ground where SRP makes sense but like all patterns they never talk about where that line is. Overuse of any pattern, methodology or principle is a bad thing and it is very easy to do if you don't think about what it is trying to achieve and when applying it no longer fits that goal.

Basically, everything in moderation and never lean on a single thing.

Hmmm... That's true, my rough litmus test is "can you explain what this thing does in fairly precise language without having to add a bunch of qualifiers for different cases?"

If you meet that bar the function is probably fine/doesn't need broken up further.

That said, I don't particularly care how many functions I have to jump through or what their line count is because I can verify "did the function do the thing it says it's supposed to do?" after it's called in a debugger. If it did, then I know my bug isn't there. If it didn't, I know where to look.

Just like with commits, I'd rather have more small commits to feed through git bisect than a few larger commits because it makes identifying where/when a contract/test case/invariant was violated much more straight forward.
