The answer, as with everything in software development, is that it depends.

A god method with 100 optional params that is usually bad practice. But a common pattern is to allow for an options object to be passed, and that object may contain 0-n supported parameters. This pattern is used everywhere, see graphql as a widely used library that is based on this.

Totes this. I've refactored far too many of these things in my day so I just about always reach for an options object if there's the slightest uncertainty about adding more params in the future.
