AB  - An exact symplectomorphism of finite type Liouville manifolds is called 'strict' if it has bounded primitive; such symplectomorphisms are well known to induce deformation equivalences and hence equivalences of wrapped Fukaya categories. Here we note that an arbitrary symplectomorphism of Weinstein manifolds, with no assumptions at infinity, can be used to construct an equivalence of Fukaya categories. We combine this with a pointwise criterion for constructing such symplectomorphisms to improve two statements in the mirror symmetry literature -- for very affine hypersurfaces and multiplicative hypertoric varieties -- where Fukaya categories were calculated for a Liouville form not known to be strictly exact symplectomorphic to the natural Kähler Liouville form on the space in question.
