Is there any chance the limit of 10 rules will be increased?

Most AWS limitations can be increased by asking support.

BTW, is there any place to log feature requests?

Become a big enough customer

I run an AWS partner who deals with many large ($millions a year each but not tens of millions each) aws customers.

It seems like the number of customers asking for a feature is more important than the size of those customers in my experience.

We have the AWS Business support plan. If you have it, you can file feature requests using the support interface.

Those underlined headers hurt the eyes. Could you please switch to a different heading style, please? Maybe smallcaps?

EDIT: And while you're listening: AWS documentation is a mess in the sense that it's way too unorganized; it might be documented but one cannot find it easily.
