I want to know the answer to the following question:
What was done to the Quranic text early in its history leaving few markedly different variants?
All the background I'm provided with is that "After the creation of this standardized canonical text, earlier authoritative texts were suppressed, and all extant manuscripts—despite their numerous variants—seem to date to a time after this standard consonantal text was established."". Is that enough to answer the question?
Answer: yes
