gmakhs its about clients who are migrated from cpanel with multiple websites
The fact that a function works on cpanel, does not mean that the same function MUST also works on enhance. The addons here do not exist to create infinite sites under a single package, the entire structure of Enhance is studied and designed to manage "multiple customers with their websites", so if you choose a platform, you have to use that platform at its best, and not try to use it as cpanel. I know it isn't easier to move them out, but keeping them inside then you have to accept their limitations.
Different PHP for different "folder" should be created as different website too, so they can have their PHP, their ini, their redis, their backup, and so on (and I'm quite convinced that what we're calling "a folder" is actually a site that lives its own life, then exceptions exist, of course, but I'm talking about the rule and not the exception).
