No, I'm talking about a very general principle that applies to
languages, libraries, etc...

For example, in Emacs I always try [and don't always succeed] to make
sure that the default behavior for a given functionality can be
implemented using the official API entry points of the underlying
library, because it makes it more likely that whoever wants to replace
that behavior with something else will be able to do it without having
to break abstraction barriers.
