I would rather focus on upcycling repairable clothes rather than promoting so much waste. Specially when a sweater I love tears, I (1) loss the sweater and (2) can't get said clothing item because as you say, the sku or even the brand may not exist anymore. Newer is not always better, both in function and form.
Point in case: Mark Zuckerberg and his style change from a anime/cartoon closet full of grey tshirts and blue jeans to a typical sugar daddy atire/style just to appeal to bigger audience without any internal change.
Stupid monkey brains.
