No, we haven't implemented an OS boot watchdog.
I'm curious to know where this is managed in Skiboot

For the time being, there is no plan to have OPAL PLDM calls for OS 
native PLDM.
We have set up and replaced the OPAL IPMI calls where we convert IPMI 
requetes to PLDM requests.
Today only2 IPMI requests are supported.
This is done in pldm-opal.c
