Finiteness conjecture for knots sharing the Floer homology of an L-space knot

Let KK be an L-space knot, meaning a knot for which Sn3(K)S^3_n(K) is an L-space for some n>0n>0. Let HFK^(K)\widehat{HFK}(K) denote its hat knot Floer homology. L-space-knot finiteness conjecture. There are only finitely many other knots whose Floer homology is isomorphic to HFK^(K)\widehat{HFK}(K). If true, this would give finiteness results for knots yielding a fixed lens space by Dehn surgery and would place L-space knots between positive-braid and strongly quasipositive-braid classes.
