About datapack and command(java)

Can add the following features to datapack/command?
This is very, very useful for developers!!
- Added new triggers such as break_block to advancements-related predicates
- Add invert selection function to component predicate of advancements related items
- Custom potion effects
- Specify items or blocks that cannot be placed/interacted with in Survival mode (instead of Adventure mode).
- Commands can be used to modify an item directly into cooldown, rather than after use
- Custom blocks/items can be added directly (even if they don't work as placeholders)
- Specified capacity container interface that can be opened with commands (for interaction)
- add or sub condition to execute (this is very useful!) ）
