Apparently IRS has kept the 1041 check-cashing operation at its own Service Centers.  That may be because most of the returns are filed by banks and other corporate fiduciaries that make online payments.

IRS used to have machines that scanned unopened envelopes to find those with checks enclosed -- the magnetic stripes would be enough to sort them out.  They probably still do that, but they also have machines that scan larger envelopes, like the ones you might use to send five checks and vouchers, for explosives or other harmful chemicals.  Maybe that's where the bottleneck lies here.
