If there is a dependency, it doesn't cause any harm to include the documents showing that dependency. It can only strengthen the case.
If the dependency doesn't exist, but the relative is close family member, the Scheme often works without showing that dependency.
When that scheme started, it was a bit unknown and people had to discover its limits by trial and errors.
But now, it can be said that this scheme goes well beyond the Statment of Intent published by Sajid Javid:

1.2. Safeguarding the rights of EU citizens and their family members living in the UK and ensuring reciprocal protections for UK nationals living in the EU was our first priority for the negotiations with the EU 1. We therefore welcome the fact that we have reached agreement with the EU on citizens’ rights and this has been formalised in the draft text of the Withdrawal Agreement, published on 19 March 20182.
1.3. We know that certainty and security of status are important. So we want to make it as easy as possible for EU citizens and their family members in the UK to secure their rights under the Withdrawal Agreement though a simple, online process.
I was sceptical about it when it started. As an observer of the UK immigration policies and their evolution, I wasn't expecting a scheme that lowers entry criteria to that point. Usually, with time to see harder entry conditions not easier. But with time, it's clear that the EU Settlement Scheme is an immigration route on its own (rather their being some sort of conversion scheme from EEA Regulations to UK law) and anyone who has any type of relationship to an EEA national or, alternatively, to anyone married to an EEA national may qualify.
If you search in the forum, there is a non-EEA gentleman married to an EEA lady and he applied for 7 of his relatives and received 7 residences for them.
