PHEVs are typically discouraged in many countries nowadays, because drivers fall into one of two categories: A) plug-in to charge on a (virtually) daily basis at home B) plug-in to charge as necessary, some of whom have no home-charging (apartment-dweller)

PHEVs make no sense for category (A) people because there is no range-anxiety if you home-charge every day. Typical drivers do 40km a day on average. Even an entry-level Tesla model 3 has >530km of range, and goes up to 750km for the model 3.

PHEVs also make no sense for category (B) people, because the PHEV has just 50km of range. So if you don't plug in all the time, you're basically driving a gasoline car with an extra engine and a battery, increasing weight (= fuel) and maintenance cost.

Various studies of real-world usage have shown PHEVs are less efficient because the behavior of its drivers. They'd be better off just driving a regular hybrid, like a Corolla.

The only area where PHEVs make sense are people who drive short-distances on a daily basis, plug in the car always at home, yet make frequent (say weekend) long trips of 6+ hours of driving without any breaks, or long trips to remote areas with no charging infrastructure. This is a pretty rare combination. Most PHEVs are traditionally owned by urbanites lured by a green dream and green subsidies, who're better off getting a pure EV or just an efficient boring hybrid.
