The thing is that we still do wrong expand_expr on that kind of MEM_EXPR, and I don't see anything that would prevent such MEM_EXPRs in all kinds of other contexts, not just in the loading of the parameters. And each of the would need hacks to cope with a BLKmode expression surprisingly being expanded to something that doesn't have BLKmode.
