MySQL (really) supports CHECK CONSTRAINT since version 8.0.16.
In this article I will show you 2 things:

In MySQL 8.0.16 the optimizer has improved again!
Comparisons of columns of numeric types with constant values are checked and folded or removed for invalid or out-of-rage values.
The goal is to speed up query execution.
