Split screen with Android Go pie

If I understand it correctly, the only thing that makes an Android ROM a "Go" version is the "ro.config.low_ram=true" entry, which brings several optimizations for low end devices and improves the performance by disabling some of the android features. One of them is the ability to display two apps simultaneously on the screen, using the split screen function. So my question is - can only the split screen (or multi-window) function be enabled on an Android pie Go ROM, without disabling all other "Go" optimizations? I'm using Resurrection Remix pie ROM on a Motorola Moto E 2015 phone.
