Back on Linuxland, the userbase realized this about two decades ago, when Ubuntu launched. Having a nice default experience was considered better than having easy tweakability, because Ubuntu could also be configured to the fullest extent in the classic Linux way of reaching into the guts of the system and rearranging things to taste. Not that I would ever recommend tweaking Ubuntu too much, but it can be done.
What about the other end? Most people who like fiddling with Linux by reaching into its internals have settled on distributions such as Arch, where this way of managing the system is expected and thus the distribution works to ensure this experience is as easy and predictable as it can be, by providing a good happy path experience for common scenarios, and providing top-notch documentation for common and uncommon customization options, or minority hardware platforms and devices.
