Hello! There are already many page cache plugins available on the WordPress plugin directory. I don’t think this would be developed as a module for Performance Lab since we’d be reinventing the wheel.
I know. But they have a lot of others things. I like something simple. Just the page cache
Thanks for your answer!
I also would like there to be more page caching plugins that just do the one thing: page caching. There are some that do that, however. Nevertheless, the intention of Performance Lab is for the features to be eventually merged into core, or at least for there to be a possibility for there to be a merge. WordPress Core has decided to not include page caching. In fact, it used to have page caching but it was removed in WordPress 2.5. Rationale has been linked to here: https://alex.blog/2010/08/10/why-wordpress-doesnt-have-built-in-persistent-caching/
