Low light makes everything more manageable.
If the high light tank has slower growing plants, what happens when things go wrong then? the plants grow in and then they stop at a certain size.

Then you have trouble.
The faster growth/higher light tanks have problems that occur much faster and more intense. You remove the faster growing plants, you also remove the balance from such tanks. You can doa little of both, some fast, some slow growth plants, but you loose more and more stability as the % changes.

You can easily mange things by simply reducing light, you do not need nearly as much as you have been led to believe.

Then if you neglect things, nothing is that bad, you save $, the tank is more stable and you can grow everything you want without such trade offs.

Topping and other pruning methods can make it easier as well.
