This type is used by component field tables to "hide" the real field type. We don't want to explain to people that 99% of field types are actually Sync`1 or something, so common types get hidden or turned into something nice. Cases where the real field type is shown are listed as "direct" as an unambiguous fallback.
The first parameter is the real field type, without generic args. So like Sync`1. The second argument is the generic contents, comma separated.
