Create a new module for site health to audit and measure heavy autoloaded data usage from the options table.

We could discuss different approaches for this or we can create and evolve the module further in different steps.

1. Informative module, we just gather the information and warn the user if needed (ex, you have more than X autoloaded options), we show them useful information of what it means or how it can be solved (exmple )
2. Functional module, we can go a step further and keep track of used/unused options, and then give the ability to users to clean up the table from the site health screen itself.

What do you think?
