The new reserved words includes two which we use as field names:

• description
• grouping

While our code to create the fields will work because it uses ` to quote them as identifiers, we'll likely want to either change these names or go through the code base and add the backtick quotes everywhere. Either approach will still mean that extensions will have to make changes to become MySQL 8.0 compatible. Using backticks will mean that extensions can continue to run on earlier versions of MySQL, and is likely the better approach. We don't want to force all extension maintainers to change references to these fields all at once when only a small number of installations will be using MySQL 8.0.

Decision: use backticks.
