The two big requirements are some kind of regular, queryable
structure to hold the components (of different types), and the
ability to filter by type. Is anything like that remotely
possible?
If the possible types are know, then there's
std.variant.Algebraic, otherwise there is a free Variant or
VariantN. They are not perfect, but maybe they are good enough
for you.

Variant is a possiblity. How is the performance with large
containers of these, since these structures will likely hold the
majority of the data in the game?
Waiting for multiple "alias this" ??
And opDispatch to respond to unimplemented components.
I'm not sure what you mean by this.
