From version 1.21.5, you need an iron ingot to craft a lodestone instead of a netherite one. I find this unfair and devalues such a useful block. You can also find plenty of lodestones in ruined portal chests, so making them cheaper to craft is just unfair, as I said.
This datapack returns an old crafting recipe with a netherite ingot.
Maybe I will backport this for 1.21.5-1.21.10 and 26.1 in a few days. Upd.: done ✅
