There may be an elite consensus, but more often than not that can differ from what is actually being spoken.
For example, in linguistics studies AAVE (or “Ebonics”) is considered like other dialects to basically have a grammar of its own that is internally consistent, and it is the first English of a fairly large population.
That’s before we get into which English is the “correct” one; there’s British English, American English, etc. for the US and CANZUK, but there’s also Indian English, Singaporean English, Euro English, etc.
