I agree with the blog post that doing a hacky solution is very helpful to understand the problem space better, although I think it's something that's challenging in an organization. In a lot of orgs, it might be viewed as a waste of time to work on something hacky. It could also come across as wasting people's time by engaging in too many discussions over PRs. People want shipping solutions today, not explorations that might need to be rewritten later. Asking for feedback might also come across as someone being unsure of a solution and needing "help" on it.
The dynamics of working in a team generally nudge devs to make more conservative moves and writing more up-front design docs, which will be slower and safer. I'm not arguing that's a bad thing, though. You need the documentation to communicate intent across an org and many other people will need to pick up the work, too. A PR may not provide enough space to comprehensively explain the overall design.
As an indie dev now, I find sketching some designs, followed by prototyping, then "massaging" the prototype into a working, shippable solution the ideal workflow. However, it only works because I'm solo and don't need to worry about getting an okay on potentially risky solutions or having to communicate and get buy-in on implementations. In a company that has lots of other devs and lots of paying customers, I wouldn't be able to do things that way, and for good reason.
