Is it okay to save a complex object without following a schema in Sanity.io?

Hey hey! Random question.
Would it be bad to have a complex object that I save into an entry, which is basically not following any schema? Think of it as a blob of data.

I'd like to do this so I can query the data inside of it with GROQ.

Just curious if there's any downside in terms of performance?

The backend is schemaless so you can plop data into your dataset without surfacing it in your Studio’s schema with no ill effect.

Thanks!
