In IPv6 as well. All designs can be solved without the need for the use of the router-I'd command, both in IPv4 and IPv6. The only issue is that within the scope of the lab, they may say don't do X or dint use command Y, in which case you may be limited as to your viable solutions.

In the case of IPv4, anyway, no?

Whether a routing process is in the global table or a vrf table, the highest loopback that is up/up when the process starts will be the RID. If no loopback exists then the highest address on any other link will be used.
Setting the RID is good design practice, and can make troubleshooting easier. If different routers have the same RID, like in an anycast design, different protocols can have different problems.
So now the question should be, what are these problems? If you know this then it will tell you when it's a good idea to set the RID manually.
