If they're mutually exclusive, you could do:
```suggestion
  using Bytes = std::vector<uint8_t>;
  using Words = std::vector<uint32_t>;
  using Doublewords = std::vector<uint64_t>;
  std::variant<Bytes, Words, Doublewords> data;
```
but this might complicate the YAML traits. We do this for protocol messages in DAP and MCP.
