We can see in release notes for 2022-10 that title field is to be deprecated from PRODUCT_VARIANT whereas when making API call using new version I am able to get title in the response.
Will we continue to receive the title field under PRODUCT_VARIANT resource?
Hi there 
You can review this changelog post. Starting in 2022-10 the title field will be automatically generated using the options translations. You can no longer write to this field, but you can still read it.
