Emre Vona on "WP Fastest Cache + Speedbooster Pack"

I am interested in using WP Fastest Cache with Speedbooster Pack but when I try I get a waing to deactivate Speedbooster Pack. I presume this is related to both being able to do minification? I only wish to use the cache feature of WP Fastest Cache so it seems that those two should work together just fine in such a scenario. Am I missing something and there is a real conflict or is my understanding correct?

No need to use Speedbooster because WPFC has the features of the Speedbooster.

These are the features I want to use from Speedbooster:
Remove query strings
Lazy load images to improve speed
Removes extra Font Awesome styles
Remove RSD Link
Remove WordPress Shortlink
Remove Adjacent Posts Links
Remove Windows Manifest
Remove the WordPress Version
Remove all rss feed links

Unless I am missing something, WPFC does not offer any of those. Furthermore, whether a feature exists in WPFC or not doesn't necessarily mean a user will prefer it for various reasons. If there is no actual conflict (my original question), shouldn't both plugins be allowed to be used. Maybe a waing that certain features can conflict would be useful (perhaps with a link to a FAQ entry explaining the potential conflicts) but not one that says the plugin needs to be deactivated.

Also, I am investigating Autoptimize but I didn't notice any waing for using that. Wouldn't that also present a possible conflict if you use all the WPFC features?

They are not important features. Just "Lazy Load" is useful. and you can use another plugin for "Lazy Load".
