Description
**Is your feature request related to a problem? Please describe.**
With `records` becoming more prevalent, the two suggested workarounds to make properties required would mean that most of the code in that record would actually deal with making Jackson behave:
```
public record Person(String firstName, String lastName) // all params optional
// workaround 1
public record Person(
@JsonProperty(required = true) String firstName,
@JsonProperty(required = true) String lastName)
// workaround 2
public record Person(String firstName, String lastName) {
public Person {
Objects.requireNonNull(firstName);
Objects.requireNonNull(firstName);
}
}
```
**Describe the solution you'd like**
A clear and concise description of what you want to happen
Flip the default, such that all properties not marked with `@JsonProperty(required = true)` or being `Optional` are required.
**Usage example**
```
public record Person(String firstName, String lastName) // all params required
```
**Additional context**
All people I encountered have been unaware of the current default behavior, and considered it unexpected/undesirable when they found out about it.
