Can you elaborate on what you think we’re missing? The one-phrase subject isn’t particularly enlightening.

There are no restrictions therefore there is nothing for us to document. Larger virtual address space extensions keep being added for RV64 (Sv57 being the latest) and we don't want to create headaches like exist on x86 where the ABI is initially 48-bit but then LA57 comes along and needs to be supported somehow. The default start address is toolchain-specific and sometimes also OS-specific.
