The code looks fine, but what is the use-case for this and this might not work, as expected, using the streaming variant of the reader.

In my case, it helps provide an immediate return when a sheet reach N rows. More efficient logic and be able to go over the next sheet or other things.
Should we add javadoc that explains the method might be indeterministic depending on the Sheet implementation?

Please do as with a regular reader the number of rows is directly present but with streaming only when the specific element has been read while processing the sheet.
