Python is an incredibly common first programming language, so we need
to keep folks with *zero* knowledge of programming jargon firmly in
mind when designing new features. That isn't always the most important
consideration, but it's always *a* consideration.
And, as Stefan notes in his reply, we also need to keep *misleading*
inferences in mind when we consider repurposing existing jargon for a
new use case - what seems like an obviously intuitive connection based
on our own individual experiences with a term may turn out to be
extremely counterintuitive for someone with a different experience of
the same term.
In such cases, it can make sense to look for new *semantically
neutral* terminology as the official glossary entry and API naming
scheme, and rely on documentation to indicate that this is a
realisation of a feature that goes by other names in other contexts.
