More ambitious is not necessarily aiming at covering with less discrimination.

I would find an encyclopedia with exactly zero article about any individual biography far more ambitious than one that cover only some, provided it would explain everything in term of structuralist perspective and consider names of actual people involved as relevant as the names of cells in a macrosized living form.

Or indeed the other way around, covering every single individual with an equal level of details, should it be done with first hand done investigation.

The middle ground that let enter only articles about people whose personal information passed the selection bias of other institutions is the lowest ambition of them all.
