"for SDIO slots" is somewhat misleading; nearly all controllers only
do one slot/device per controller. The designware controller can do
multiple slots, and that adds a bit of driver and binding complexity
for something that seemingly not a single vendor has actually
implemented.

The Marvell 8688, just to name one, does both WIFI and BlueTooth over
the same SDIO controller using separate functions/slots.

But that is logical functions within a chip, not multiple discrete
chips (i.e. slots) with their own reset, regulators, etc. There would
still be a single set of external controls per host controller I
think.
