If β is natural numbers and β is rational numbers and β€ is integers and β is the rational numbers, what are π and π?

Not aware of any specific usages, but maybe they're used as meta-sets. e.g. "consider a set of numbers π and a set of numbers π ... etc, which can't be done with the defined letters.
Unicode originally only had the double-struck letters for the defined sets β, β, β, β, β, β and β€, but the full alphabets were later added at higher code-points with "reserved" gaps where the defined seven letters would otherwise appear.
(Complex, Hamiltonian quaternions, Natural, Prime, Quotient (rational), Real and Zahlen, a German word for counting numbers, for anyone wondering. Also, β not getting "β" because β couldn't have "β" is kind of funny.).
