Increase Theme Settings Limit

There is a way to increase the limit of the theme settings? I mean to set more than 15 theme settings. Thansk!

As per the docs, the settings count is intentionally limited to 15, meaning you can’t change it without hacking the core.

But what’s the point of limiting theme settings to 15? If I have to make a theme, I have no possibility to offer any customization changes. Virtually all sites remain the same, apart from the color and a few other changes. I really don’t find any sense in this.
