To ‘%base-packages’ for example? It doesn’t really matter.
What’s important is to never ever remove a public variable, or change
the signature of a public procedure, without prior deprecation period
(at least for interfaces that one may use in their System or Home config
files.)
gnu/{services,packages}/*.scm contain bindings that have been deprecated
for years. That’s probably excessive, but lack of a deprecation period
would unnecessarily upset fellow users and then we’d have to channel
their anger. :-)
