I don't know if I can give an opinion: the default behavior should work in most cases; if one needs fine-tuning, there might be a way for that, but in the end nobody might end up using it. I think people normally don't want to use --param= in arch-specific compiler flags; they might not be even aware of such fine-tuning. The example I gave comes from a real-world code, in this case an assertion check that the symbol is aligned (iirc). Are there plans to backport this to the other branches?
