I'm always frustrated when slicer requires a lot of parameters to work.
Describe the solution you'd like
For the reader-based interface we can check if the reader passed implements Seeker as well and if so --- getting the payload size from it is a piece of cake.
Additional context
539, this can't replace it, but can be a nice amendment, buffers and files implement Seek().
