Consequences of slave count limit violation for CI867

As far as I have heard, CBM used to popup a warning when the limit of 70 slaves was violated per CI867. However, when I violated that number by far in 5.1 FP4, I did not receive any messages, I was even able to compile and download to a soft controller.

We are going to use TCP gateways in an application with 202 pieces of DIRIS A40 energy analyzers and we intend to connect a maximum number of 13 analyzers per gateway. I would like to make sure about the consequences when we violate the 70 total slaves per CI867 and 4 RTU slaves per TCP gateway limitations. Is it only about the response times, or would there be more serious issues like unstable communication, etc?

Thank you for your comments and suggestions in advance.
