> {code:java}
> 2.19                  2.20
>  A                     A
>  B                     B (deprecated)
>  C                     C
> {code}
> While RU is in progress, field B is still filled by the previous logical version's code, so it must be transmitted:
> RU in progress (logical version is 2.19)
> {code:java}
> 2.20  <------------>  2.20
>  A           A         A
>  B (filled)  B         B (filled)
>  C           C         C
> {code}
> Once RU is finished, the new logical version no longer fills B, so it is always null and we don't want to send it anymore. But the nodes have already agreed on B, so it is still transmitted:
> RU finished (logical version is 2.20)
> {code:java}
> 2.20  <------------>  2.20
>  A           A         A
>  B (null)    B         B (null)
>  C           C         C
> {code}
> We need to support excluding deprecated field from transmission.
