Can you have a childless summary node if it is disabled in FCGL?

In the FCGL app, on the dimension level, we use the "predefined" validations including the one called "Summary Node With Missing Children." We recently had a parent that we needed to disabled and move the children to a new parent. We turned off the "Summary Node With Missing Children" validation in order to move the child out from under the summary node parent (which is disabled).

How should we handle cases like this so that we can turn the validation back on? Will there be any issues having a disabled summary node without children in OFC?

We would like to avoid making dummy children just to use the validation.
