I think it’s a size constraint. Bigger sensors also require larger lenses. In regular DSLR world a micro four thirds sensor, the sensor size is half the size of a traditional full frame sensor. The lenses are also half the size of a fullframe camera’s lenses and require far less glass and weight.
We can fit 3 smaller sensors with three smaller lenses in a smartphone. Trying to make any of those sensors bigger will require more space than a phone can provide.
Because we have to have smaller sensors, digital zoom reduces fidelity of images. Having multiple lenses optimized for various focal points mitigated this issue
I’m no expert just a hobbyist take my word with a grain of salt lol
