Speaking as a non-network specialist, it actually looks logical to me to be
given an address if I iterate over a network (the same way that, if I iterate on
a list, I get individual elements, not 1-element sublists).

I don't understand why you think the network mask should be part of an address.
An address is just an address, it specifies the location of a host, not the
configuration of the network surrounding it. If you look at an IP header, the
destination address doesn't specify a netmask.
