Because most Standard Model particles are absorbed in the dump, beam dump experiments are also suitable for studying weakly interacting particles like neutrinos.
Notes on verification
Directly corroborated by Wikipedia source text and independent sources (T2K, SHiP experiment papers) explaining the same physical mechanism of beam dumps filtering out strongly/electromagnetically interacting particles while allowing neutrinos to pass.
