There is no single true solution.

Yeah direct endpoints are Camel context wide. You can use that to link
2 separate routes if you want.
If the 2 routes must be fully separated then of course the endpoint
names must be unique.

Global mean per CamelContext. There is nothing that is Super global
and works on all CamelContexts.

There is a ticket though to add this to Camel in some form of template
routes etc.
https://issues.apache.org/activemq/browse/CAMEL-1919

Part of it is already done in the Java DSL. The Spring DSL is missing.
This should also help with reusing error handler settings,
interceptors etc. among multiple route builders.

This will also solve the naming clash issue as all endpoints are only
global within the CamelContext.
