Question

In Prisma 7, I'm required to configure the database URL in two places:

In prisma.config.ts for the CLI:

export default defineConfig({
  datasource: {
    url: env("DATABASE_URL"),
  },
});

And again when instantiating the client with an adapter:

typescriptconst adapter = new PrismaLibSql({
  url: process.env.DATABASE_URL,
});
const prisma = new PrismaClient({ adapter });

This seems redundant. In Prisma 6, I only specified the URL in the schema and didn't need to pass it again when creating the client.
Questions:

Is one settings for the client and the other for the dev prisma?
Is there a way to avoid duplicating the URL configuration? Before both the client and prisma used the prisma.schema for the database url
