Shakir Brahui's rise of a brahui consciousness is an unreliable source. It's a political text, promoting a political ideology (Brahui nationalism), which shouldn't be included in a Wikipedia page solely about ethnicity. It would be like citing white supremacist texts in the Wikipedia page about White people.
And it's unreliable and wrong on many of it's wording. It says that Brahui is spoken natively by the Brahui language, HOWEVER a large part of the brahui people adopted the language (this being recorded in their folk history as well as written sources). This includes the Lehri, Langove and Bangulzai tribe,who previously natively spoke Balochi, or tribes like the Zehri or Mengal, who previously spoke Jadgali.
Second is the word Brahuistan itself, which actually isn't used by Brahuis for their homeland.Instead they call it Balochistan. He says that folk tradition of Brahuis calls their area Brahuistan, yet one of the most famous Brahui folk songs Danah pa dana calls the area Balochistan, if you want to confirm this go listen to the song and also read the English translated captions of the song.
Lastly, he says the British contemplated renaming the area Brahuistan in account of the fact that Brahuis ruled the region and were a majority, which he is right about. However the british went forward with Balochistan not because of the great game (i don't know what the great game has to do with this) but rather the wishes of the Khan of Kalat himself, who styled himself Ameer e Balochistan.
