Uhm... I'm not aware whether xstreamtodev uses a save interface to the system.

Let me check (or see yourself; the xstreamtodev and friends sources are 
somewhere on ftp.netbsd.org /pub/NetBSD/arch/amiga/misc)

Loadbsd uses the AmigaDOS calls to read the kernel off the Amiga filesystem
and should be safe.

The bootblock will have problems even on OS3.5, as the bootblock calling
interface didn't change (and anyway, I don't know a single person with OS3.5
in ROM.)
