It is difficult to say. Modern protocols are such a huge complex mess, that
TCP/IP stack were a minor concern here. In my experience UDP is pretty rare
in process automation. For example XCP runs on top of UDP. TCP/IP is more
widely used, but like UDP almost always with something on top of it, e.g.
DLMS, ModBus etc.

Anyway, I would like to stress that it is not data exchange which makes
troubles. Before you get on data, you must configure the slaves. This stuff
is in relation 90 to 10 (or more) to data exchange. So, if Ada standardized
the exchange, that would be unusable anyway.
