Thank you for responses! Turns out my scene contained hanging leaf transforms and it was the issue. I removed them and now it works just fine.
Regarding the root node issue you have mentioned. I've noticed the variable name "nodeWeCannotRemove" and already tried adding a dummy Group above it but without it Optimizer will just apply the transform and set its matrix to identity. So it should work anyway.
