Like with every not yet existing functionality, it is best to create an enhancement through the idea portal. The only way your question will be answered if someone working on it at ServiceNow will read your question. The road maps and what is being worked on are not publicly available.
But why not copy the ITSM board and add everything there you want/need to see, including HRSD stuff? If it will be a big help, like you say, I would start creating it instead of hoping it will come OOB.
Please mark any helpful or correct solutions as such. That helps others find their solutions.
