FICO to incorporate buy-now-pay-later loans into credit scores

Does anyone else live in a place where there isn't a visible "score" for how valuable you are, but rather only a "credit check" for how risky you are, which is performed if you apply for new credit (buying anything with an invoice, getting a credit card, or taking any other kind of loan)? Meaning that if you have a good income and no history of failing payments, you are basically passing the check with flying colors, and will have the same "score" as someone who has had tons of well-served credit before?

This thing where the score as in "risk" and score as in "business opportunity for lenders" is intertwined, and creates weird incentives for consumers, is that only a US thing or do any other countries have something similar?

Credit scores aren't a score of how valuable you are, they're a score of creditworthiness or how unlikely you are to default on a loan. The largest factors are age of credit and payment history. Utilization is also a factor. Someone who occasionally misses payments and has high utilization is going to be more profitable but higher risk to lend to.
