Perhaps you misunderstood. The issue is that adding slew-controlled drivers
to the driver library is expensive. Si companies at present aren't doing it
because there's no perceived demand, so the only way to get the slew-controlled
drivers is to commission their design. For the first OEM (company A) to do
this it's a hit to both the budget and the schedule, which has to be traded off
against doing more SI work in-house.
OTOH Company B, who book their order six weeks later (as the cells make pre-Si
qual) now has gained six weeks of schedule disadvantage relative to their
competitor A, and can send the NRE that they didn't have to plonk down to
their stockholders.
IOW it's the implementation, not the state of the art _per_se_, that costs
without necessarily providing competitive benefit (or even negative
benefit.)
