dictionary LanguageModelPromptOptions {
object responseConstraint;
boolean omitResponseConstraintInput = false;
AbortSignal signal;
};

dictionary LanguageModelCreateOptions : LanguageModelCreateCoreOptions {
AbortSignal signal;
CreateMonitorCallback monitor;

sequence initialPrompts;
};

A developer I heard from complained that, this makes it so that when unexpected values are passed to prompt options. Like initialPrompts for the PromptOptions - it gets silently ignored.
