I don't think Bardock was fully retconned until the Granolah Arc. In both Minus and the OVA he cares about his fellow Saiyans but shows it in different ways.
OG Burdack didn't care about his family. He only cared about his crew because they fought alongside him on the battlefield. Obviously he didn't want his whole race wiped out (most people wouldn't), but we see that he didn't get along with the other Saiyans at the bar.
Minus Burdack clearly loved his wife and kids. He even admits that Gine's softness was rubbing off on him (whereas we didn't even see Gokuu's mom in the TV special. It's pretty much implied that it was just some Saiyan random woman who Burdack had no romantic attraction to). The Granola arc goes right along with this interpretation of Burdack; he was reminded of his own family when he saw Granola and his mom.
The only thing that the new continuity keeps is Burdack confronting Freeza's army in an attempt to stop him from destroying the planet. Everything about his old crew has been retconned away (we see them in DBS Broly, but it's clear that Toei just felt like reusing their designs as cameos. Toriyama probably didn't even remember them); the circumstances behind Burdack's final confrontation with Freeza have changed.
