Family plan size limit too low: Do people really only have 6 persons in their families?

Hello everyone!

For some while now I really want to subscribe to the family plan but the member limit of 6 is an absolute blocker.

My family already has a custom email domain and had it for at least 20 years now. We are currently three generations with parents, children and grand children. Currently we are only 7 but we will be more, eventually. Of course our current simple mail provider allows basically unlimited mailboxes so every member of our family can have a `@familyname.tld` email account.

Without a doubt joining Proton would be a good thing but it appears privacy is only available for family with up to 6 members. Somebody would have to be excluded from their already existing online identity because we could not migrate all accounts to Proton. And new family members (be it through marriage or birth) would not be able to get an account with their family name because they joined the family too late.

Don't get me wrong - I don't think the limit should be removed.

BUT: Why can't we add more seats to a family account by paying an additional proportional amount? The business plans can do it, why can't the family plans? Before somebody suggests it: The business plans are way more expensive and are not a valid workaround for the family size limit.

This post is half rant half suggestion/wish. How about you? Do you think 6, with no option to expand it, is an appropriate member limit for a family plan?
