Routes in paths are now somewhat uncommon, but are not obsolete and

They've been strongly deprecated since RFC 1123 (dated 1989) which states
that this is for architectural reasons. Therefore I think it's legitimate
for a modern description of the architecture to omit source-routed paths
on the grounds that they are ana anomalous historical relic.

Strongly agree.   Actually I'd go a lot farther and say it's legitimate
for a description of the architecture to omit almost everything at that
level of detail, historic or not.
