> I still don't like this approach, sorry. And still don't understand why you prefer it. Just imagine that we would need to send another type of System Information, e.g. SI4. This would require you to bump the protocol version again. If it's possible to avoid bumping the version, I would definitely avoid doing it.

You can easily support new and old versions  (be backward compatible) if you add the fields at the end of the struct, I see no problem there. Older implementations won't see those fields and won't access them.

The only benefit I see in adding a new message type to send SI information is that if they change more frequently, then we don't need to send the entire info_ind to the pcu and make it parse all of it again.
