Make fireworks interact with more mechanics

IMPORTANT: here i am talking about explosive fireworks, not about those for elytra (except for a point)

Introduction:

Fireworks are pretty expensive to craft in large quantities. They do quite some damage though, which is good, since they are shootable with the crossbow and with dispensers. They can totally lead to some interesting mechanics. The problem is that they are underpowered for some important reasons and my post is about this.

First point, making them ignite ender crystals:

Yesterday i was trying to kill the ender dragon quickly cuz i needed to do a thing in creative. I aimed and fired at the crystals with my multishot quick charge crossbow and fired lots of 7 stars fireworks (the most powerful) to them. Nothing happened. What the heck, explosion that take 19 hearts of damage were happening all around the crystals, but they were staying there, like they were indestructible. Both explosive and not explosive fireworks should ignite crystals: even a snowball can, so the fireworks really must.

Second point, making them damage the ender dragon:

The ender dragon is not immune to explosions and with all the resources needed to make fireworks, it is a real shame that they do not damage her in the slightest. Fireworks should damage the ender dragon.

Third point, making fireworks ignite tnt:

Well, this block really is a block that should interact with fireworks. The only reason why it doesnt is because fireworks do not destroy blocks, but, i mean, why not making some sort of check to see if there are TNT blocks to ignite nearby?

TLDR:

Make explosive fireworks ignite crystals and TNT and make them damage the ender dragon
