The relatively centralised style of Hololive also lends well to spreading the word of new debuts really well. Even if you somehow missed the news of the debutees in the weeks leading up to their debut, you'd still know they are debuting because the other talents will talk about it, and if you somehow missed all of that, there is still the post-debut streams of the other talents where they talk about the new debutees. This means that even if you only watch your oshi and nothing else, you would know there are new debutees.
Do I need to watch their streams? If I'm interested, sure. But the most important part is that viewers know they exist, that they know that so-and-so is part of Hololive nth generation.
On the other hand, how many nijis are literal whos?
