1. HO guidance says that "direct" family members who aechildren over 21 or parents need t oshow dependancy:
Here, page 11-12

2. In the same document (page 12) it says that:
If they cannot provide valid proof to show they are currently dependent on their EEA national sponsor, or the sponsor’s spouse or civil partner, you must check the guidance for extended family members to see if they satisfy the conditions of regulation 8(2) of the 2016 regulations. For more information, see: Extended family
members of EEA nationals.
3. If you look at those eferences:
http://www.legislation.gov.uk/uksi/2016 ... ion/8/made
or page 8 of
https://assets.publishing.service.gov.u ... s-V6.0.pdf
Then you see that it is enough if a non-EU is a "relative" and:
is a member of their household and either:
o is accompanying the EEA national to the UK or wishes to join them
o has joined them in the UK and continues to be dependent on them or to be a member of their household
And page 16 of the last document says it is enough to submit:
evidence of membership of EEA national’s household, such as:
o utility bills
o tenancy or mortgage agreement
o other evidence of cohabitation
My reading of all this is that one dos not need to show financial dependance if there is "evidence of cohabitation".
