PS4, Line 17: Description of .init section for ELF:
            : 
            : This section holds executable instructions that contribute to the
            : process initialization code. When a program starts to run, the
            : system arranges to execute the code in this section before calling the
            : main program entry point (called main for C programs).
> > I wonder if we could first rename existing .text._start and .text.stage_entry both to .init. […]

For x86 bootblocks .text._start must be at most 64 KiB from .reset. Or in other words, C_ENV_BOOTBLOCK_SIZE must not grow over 64 KiB while latest soc/intel have reached 48 KiB already.

There is followup CB:47970 that locates this newly introduced .init after .text.* rules.
