I'm always frustrated when message binary does not change but JSON does

currently, when proto message is extended with new field(s), they start to appear in producing JSON even when unset. I see following cons in this:

change as such
bigger size with the same utility

i don't see any pros

Describe the solution you'd like

omit empty fields

see nspcc-dev/neofs-sdk-go@3c286a4986/internal/proto/encoding.go (L70)
