Yup. And you can’t close the WGs without terminating the contracts (if any) of the people associated with it.
Also, as per the proposal, if someone thought it was a good idea to create a WG and it turns out that it wasn’t a good idea/plan after all, another member (that being me) can similarly write up a proposal to close it. Then it’s up to the voters to make the final decision.
This is no different from what happened to the Ape Assembly some months ago. Someone created it, amid much fanfare, we did a LOT of work with it. Then Amplify wrote up AIP-347 that essentially killed it, thus side-stepping an AIP-358 which I written to try and save it.
