Both options have pros and cons but IMHO the cons for replaceable are more.

Since 2020 phone hardware and especially battery has become much better, reliable and long lasting, at least at not dirt cheap ones. It will fail long after the screen brakes or the software updates stop. And a replaceable battery degrades the design.

On the other side a new battery makes an old phone like new. But again it only costs 15-20E to change it in a non-repl phone.

The only real reason to promote battery repl is to reduce e-waste.
