Does anyone know if they're going to fix the mob spawning in caves or leave it as it is?

I feel like it's a little wrong that I can go down a cave for 1 minute and not encounter any mobs, then when I get to a dead end and think, "Hmm, I took the wrong path, I'll go back the way I came and this time take the right instead of the left,"

And when I go back the same way I just came, there are like 58 mobs that weren't there before.
