This looks great! One thing we could do to improve this further is trying to shorten it. Would it be possible to have one dynamic template per distinct mapping definition? That could be achieved today using regex patterns, otherwise I would be glad to work on
elastic/elasticsearch#66364 and allow for matching on a list of fields, like @ruflin suggests. This would shorten the file considerably and would make it easier to digest?
Not so relevant comment: Is using the nested type really necessary? Among other issues, that will prevent us from using subobjects:false.

I would rather stay away from this and have elastic/elasticsearch#66364 as I think it is too easy to make mistakes in long regexp and I think there is also chance it gets inefficient.

I think the bigger problem here is that ECS started to define it in the first place 👎 @P1llus My assumption / hope is that nested does not exist in the core fields, potentially one more reason to split it up.
Also if we have some odd fields like nested, these could be put in their own / special component template so anyone not wanting these can skip them.
