Not entirely sure if this counts as a feature request but it definitely is inconsistent, makes no sense and is pretty inconvenient. Also, as this already applies to nether stars, the fact it isn't extended to other places that make sense seems like a major oversight.
Blast-resistant materials such as bedrock, obsidian and full blocks of netherite can withstand any blast achievable in vanilla survival when in placed block form. However, if in item form, absolutely any explosion can completely delete them from existence, which is outright nonsensical. Nether stars, on the other hand, are completely immune to all explosions as an item.
The expected behaviour would be that none of these items are destroyed by explosions.
Items resistant to explosions could be controlled by an item tag.
This closely relates to MC-123217 as it also results in normally blast-resistant materials becoming susceptible to most explosions.

A block that is physically placed in the world has completely different abilities and statuses compared to when it's in item/entity form. This is the case with everything. Buckets can hold lava and yet they burn when dropped into it. Crimson and Warped planks do not catch fire but they are still destroyed when dropped into fire. This is behavior that has been in the game for extremely long and that they've continued intentionally implementing, and within game logic it does make sense. Items exist as entities to allow you to pick up or transfer any objects and use them in their proper physical states. They aren't ment to retain the physical properties that they otherwise might have in their block/placed/"physical" form, but rather might have their own seperate properties depending on item. Netherite items don't burn because the developers wanted the player to have a solution to items burning in lava when dropped. They could have just prevented most gear from burning and it would have been logical since buckets can already hold lava, but they want dropped items to have seperate properties. I can understand if you want Netherite items to have the blast resistance property in dropped form, but I wouldn't call the lack of this an oversight. This is definitely a feature request.
Can confirm, although, as you said, this may be a feature request.
