Sounds like a business opportunity. If a third party hasn't made any yet they likely will soon. One problem with encouraging common parts is that it may limit innovation, and it may also incentivize a manufacturer to keep a flawed design. It's just as likely that samsung realized the shelves in that model sucked and made a new one. I think it would be better to mandate manufacturers keep stock of replacement parts for X amount of years, and/or they must release design documentation for third parties to make parts.
