These I honestly didn't even think about before, but now, after you've
brought them, I'll pay attention, thanks!

It's nice we've reached mutual understanding!

The only remaining issue then is if we just go and do the change of -m

Looks like we are rather safe to just go, as it's unlikely there will be
any real breakage. What do you think?
