Description

Generically, wide table schemas will bypass the type system:

https://github.com/JuliaData/Tables.jl/blob/2cb13998e856692ed273c931b83477caf8b7b020/src/Tables.jl#L477-L483

But not for MatrixTables:

https://github.com/JuliaData/Tables.jl/blob/2cb13998e856692ed273c931b83477caf8b7b020/src/matrix.jl#L40

Maybe the branch should be put in the constructor, such that it is done for any table type?

Research direction

Compare the wide-table handling in src/Tables.jl at lines 477-483 with the MatrixTable path in src/matrix.jl at line 40. Read the linked Arrow.jl pull request for related context, then determine whether Schema construction should apply the same type-system bypass consistently across table types.
