Whoa!  There's got to be *some* meaning there.  Afterall,
it's an identifier, isn't it?

(You were talking about a URI, and then all of a sudden, the
antecedent of "it" became the printer.  Did you notice that?)

Are you saying that when you stick certain groups of services
together into natural, logical bundles, they take on a sort of
meaningful identity, and you'd like to be able to name that so
you can refer to it over and over and use it?

Looks quite interesting.....

Er, you still have the problem of tying and re-tying in response to
changes, so you're no better off.   Maybe there's another way....

You may prefer a duck pond. :-)
