What is the current behavior?

Issue Number: #1425
In this old issue from the graphql repo it is suggested that PartialType shouldn't inherit property initializers which makes total sense since a CreateCatDto may provide default value for some fields but a UpdateCatDto that marks all fields as optional should leave all unset fields undefined to avoid unwanted changes.
We can make this an option but it feels like it should be the default behavior since I can't think of any case where it can be useful.

What is the new behavior?

PartialType doesn't inherit property initializers.

Does this PR introduce a breaking change?

• Yes
