I am honestly not sure as to what the benefit of that is compared to the approach of CalyxOS with MicroG. It has worked for me perfectly, except for one app, BeReal for some reason gives a pop-up telling that Google Play Services is missing, even though I already have MicroG fully setup and working. Other apps have all worked fine, including Google Apps like YouTube and my banking app.
I mean, good for you. I kinda need my sandboxed google play services, despite wishing I did not.
