Multi-column value conversions were initially tracked by #13947 as a way to enable value objects, but we decided to instead implement them using complex types.
This issue tracks using value conversions as an alternative to complex types.
Pros
How properties decompose into columns is more flexible (e.g. two properties can be stored in one column or viceversa)
Cons
Opaque to queries (i.e. individual properties participating in a multi-column value conversion can't be used in conditions or projections)
