That's impressive!

Why prioritize adapting legacy C tests over using D's `-betterC` 
mode to validate the AArch64 backend and low-level codegen?

Because risks masking AArch64-specific codegen flaws (e.g., 
register pressure, non-uniform integer widths, or C→AArch64 ABI 
mismatches) that only raw, unaltered C exercises.
