#2 Is low cost. However, the information about the remaining capacity quickly becomes outdated if not used immediately, so we also need #1.

And #1 can be also used from slow path, e.g. for telemetry purposes.

So I vote for providing #1 and optionally #2.

I also considered if a _bulk function would be useful in addition to the _burst function. But I think that the fast path application's decision is not binary (i.e. use DMA or not), the fast path application would want to process as many as possible by DMA and then process the remaining by software.
