Why is Bottomless Well and Tightly Sown wheatfield for such high levels?

I don't really understand why...

They are overpriced and not many people use them. Why would you build Tightly Sown wheatfields when they cost exotic wood and granite and contain only 800 wheat? You can get Medium Wheatfield for just hardwood planks and marble (both are easy to get and cheap to buy).

It should be more like 1200 wheat and level 40.
I dont really know many people using it like that. Why would they... just dont understand the reasoning. Packed wheatfield is 3000 wheat and its easier to get.

they are not even that good first it's not bottomless and with the refills wheat fields can be loaded up cheaper than building any of those two

But silos provide the best answer to wheatfields.

Get silos and never build wheatfields :)

I'm just saying that they are useless. Devs should buff them or just remove them. No reason for them to exist, when no one is using them.

If they won't help you, ignore them.
