Comment 8 for bug 1776189

We did a short brainstorm/bikeshed sesssion on the name and decided to:
- use "hpb" for host-phys-bits abbreviation as the former -large could be a lot of other things
- acked on not start type proliferation in general (only in very special cases)
- if possible use a "+" instead of "-" in the type
- Add desc in text line for the type
- add a doc or news entry along the change
