I didn't say the BB assumes inflation, I said it needed fancy physics such as inflation to explain the current state of the universe.

> The BB is compatible with inflation, but theories of inflation were proposed well after the BB theory itself.

Exactly, and the reason these theories were proposed was to 'fix' the BB itself. So of course they are compatible with the BB. There is no observation that asks us to consider something like hyper inflation, except if you assume that there has been a BB.
