I believe it's part of the language design, a phrase you'll find quite a lot in Python language discussions, especially is more esoteric features is; "We're all consenting adults".
There are certain areas of the language which may not behave exactly the way you'd be expecting, if you're new to it.
These usually have an unusual syntax, which will cause you to find out more.
If you know what you're doing you cruise straight over, but if for any reason you're unsure, you're forced to find out more before continuing.
It's not designed to stop you, because "We're all consenting adults", but that doesn't mean it's going to encourage you to do something that might be harmful.
Unless of course you're in Belgium where all junctions are by default preference from the right (so like a mini-roundabout but with no markings), which are opposite preference from roundabouts here which are preference from the left. But some junctions are labelled, some aren't depending on whether the local council could be bothered, some people will forcefully use their preference and risk a crash but 90% will ignore it.

They're basically the mini-roundabouts of python.
