What decision should a developer make if they want an identical Breadcrumb as the core but with an additional icon?

The optimal decision for a developer who wants to create a Breadcrumb component identical to the core version but with an additional icon is to re-use the core breadcrumb and add an option to upload the asset. By leveraging the existing core breadcrumb functionality, the developer can maintain consistency with the system's design and behavior while adding the desired custom feature. This approach facilitates easier maintenance and integration, as the core component is likely already optimized and tested within the environment.

Utilizing the core breadcrumb as a base allows for customization without starting from scratch. Furthermore, it promotes reusability within the application, reducing redundancy and ensuring that any updates or fixes to the core component automatically propagate to the new implementation.

Developing a new custom component, while possible, would require additional effort and time, as the developer must ensure that the new component mirrors the functionality of the core version, which could lead to potential inconsistencies or duplications. Requesting Adobe to modify the core breadcrumb component goes against best practices, as it can lead to complications in version control and maintenance, and may not align with the company's customization policies. Lastly, using a different framework to create the breadcrumb could lead to compatibility issues and would divert resources from leveraging the already established core infrastructure.
