@jmcnamara commented on GitHub (Aug 20, 2024):

Unfortunately adding support for xlsb is non-trivial and would take a lot of work to duplicate all of the xml writing code with equivalent BIFF binary writing code. It is also much harder to debug when something goes wrong. I know this from experience of working with the xls file format.

So overall this is a "won't/can't fix".
