regarding GP Sections

Hi,

I am planning to build a website that uses GP Sections rather extensively, both for posts and pages (no page builder).

My questions is, what would happen if say in the future I no longer use GP and switch to other theme? Will that mess my content?

I am not planning to switch to other theme any time soon since I am super happy with GP. The only reason I am asking this question is because I had bad experience with Divi of Elegant Themes in the past. Divi leaves a gigantic mess when I change to other theme. Shortcode tags are all over my content. It's a serious problem especially if you have lots of content on your website. I wonder if that will also be the case if I use Sections.

I actually experimented with it earlier. When switching to other theme, I do not see Divi-like mess at all, which is really impressive. But since it's a test site, there's only a handful of posts and pages there. Not sure if it also won't happen with larger website.

Thanks in advance for taking the time to reply to my question.
