Many of the Qualcomm development boards feature DRD capable
type-c ports. However these boards differ from smartphones in their
usage, and it's generally preferred that they would enter host mode by
default when given the choice.
This doesn't affect connection to a host-only PC, since the controller
is still DRD capable.
The RB1/2 are a special case, since they feature an on-board USB hub and
a manual dip switch to toggle between it and the type-c port. Preferring
host mode offers a useful hint to the software if it doesn't feature a
fully DRD capable USB controller driver, it can just use the default
mode (rather than defaulting to peripheral mode unconditionally).

It's really not what I observed on sm8550/sm8650 QRD/HDK, as the power is setup for peripheral by the bootloader and without an actual UCSI/PD negociation it would only be functionnal as peripheral mode. So this is definitely untrue on sm8450/sm8550/sm8650 HDK/QRD/MTP.

UCSI doesn't care about role-switch-default-mode, it's the default fallback role to set when no role was explicitely set by UCSI. Setting host won't make it work because the power support is handled by the UCSI firmware. setting role-switch-default-mode = "host" will make the USB port unusable if UCSI fails to start since it's physically set to peripheral mode.

Let's not mix the source/sink and host/peripheral, those are independent. But I see your point. Neither TCPM nor UCSI check this property.
