I did not follow up on it as it will also require to change the printing
api. The printing api needs to support the same number of pages which
requires quite a bit of work.

Additionally we are currently memory bound in most cases because even an
empty sheet is large enough to make 32bit computers crash with out of
memory exceptions for the supported 32000 sheets.

So currently I think it is really low priority and we can work on that if
we think that there are real use cases. Until then we have limited
ourselves anyway to "only" 10000 sheets.
