We really shouldn't argue about that, because that is the crux of the
difference.

If \If\, conj.
   1. In case that; granting, allowing, or supposing that; --
      introducing a condition or supposition.
      [1913 Webster]


While \While\, conj.
   1. During the time that; as long as; whilst; at the same time
      that; as, while I write, you sleep. "While I have time and
      space." --Chaucer.
      [1913 Webster]


Of course there is overlap: both are conjunctions, both depend on a condition,
but the fundamental difference is that of duration.

Your two examples are not actually equivalent:

"Make hay while the sun shines" implies that making hay is a process you can
continue for as long as the sun continues to shine;

"If it's sunny, make hay" implies that making hay is a once-off job that you do
once, provided it is sunny, and then go on to do other things even if it
remains sunny.

And that is why the English proverb is the first, not the second.

enough, things got worse.
