I'll still disagree. The point if EI was to be a step above base, especially when base was out of the box FX, and the point was to resolve the most egregious visible bits, such as ab plate buttons, etc. Centurion is for pimping out a kit as far as Legion standard allows. This should really start as a Centurion nice to have (as it's not visible), and if people are finding it way too easy to do, one could always make it mandatory for Centurion. Going to EI makes no sense.
It's like the bracket assembly method. Should never be part of Centurion, as the goal of the legion is not to replicate props, it's to replicate what is seen on screen. You can always make such things optional for now and see how it plays out on Centurion.
But when we have such a low adoption of EI already, it seems at odds to the point of the program to spend time adding yet more requirements to it rather than trying to get more people to hit the existing bar...
