What happened to GetCapabilityMessage?

[djromberg]

According to the master's history, the GetCapabilityMessage class was removed here:
ddafed4#diff-3df11a2df2a245be2a7fc11d14f6a245 on April 25, 2016.

There seems to be no replacement outside of igtlCapabilityMessage.h. After upgrading to version 3 I need to adapt my code and wonder how I should proceed. This change is almost 2,5 years old and I also wonder whether I miss something.

@tokjun @lassoan Were v1 messages back-supported to enable the v2 query mechanism?

Any news on that? I think it is a bug. On the other hand, no one seems to require it. So maybe the protocol should be adapted. I wonder whether the CAPABILITY message makes sense without a GET_CAPABILITY message.
