I can't find any mention of the stop function in the documentation, so I'm unclear whether it is intended to be used in this way. As far as I'm aware, using effectScope is the only documented way to dispose of a computed manually.

#10397 deprecated the effect property of ComputedRefImpl, but it seems to have been kept for backwards compatibility:

https://github.com/vuejs/core/pull/10397/files#diff-95734490ac7bb277f876f1c6e635a2718f5f8ac75615d0d72403df5a8903e652R55

That backwards compatibility doesn't include the effect.stop() method, which is needed by the stop function.

Update: After reading the PR description for #10397 a bit more carefully, it looks like a computed can no longer be stopped, even using effectScope. The documentation for effectScope may need updating, as it currently mentions computed.
