I don't think I suggested that someone should wait, just that the opportunity to talk about blockers (ask for help) was important.
Each of the loops is about shortening the cycle before you discover problems. These are seen through the lens of traditional waterfall software development. The problems vary in nature, from technical blockers and dependencies, to unrealistic deadlines and expectations, to not building what the customer wants (why we involve the customer early and do showcases).
In some ways the more mature your team becomes the more you can move past some of the rules. The 'standup' was designed to avoid the meeting becoming overly long, everyone would become foot sore. Once you understand and embrace making the meeting not turn into an hour long (or even 30 min long) meeting, the standing itself becomes less important (which is good because remote teams make this harder).
Similarly, there are even shorter cycles of being able to remove blockers now. Granted Slack team channels can be a blessing and a curse, but it does make it possible to just put problems out there for consideration[0]. These sometimes go unanswered though, which means that the aforementioned standup becomes a backup.
I've been part of so many lean/agile teams that all do things slightly different. The highest preforming of those were the ones where the trust was the highest. Great teams become "a rising tide lifts all boats"[1].
I hope you don't see this (and the previous post) as an attack. It's near on impossible from a distance to really see. It felt like a red flag but that's two lines of text on a semi-anonymous message board.
[0]: draft PRs also fall into this category. Though again, devs have to find time to read them.
