KrylovKit still uses the julia LinearAlgebra standard library, or thus BLAS and LAPACK, for dealing with the small problems projected on the Krylov subspace. So it is currently restricted to the same eltype
s as LAPACK. I would love to see this changed in the future, but I don't expect to have any time for this anywhere soon.

Thanks, indeed I tracked down some issues in the Julia repo itself. Could it rely on GenericSVD?

It could, but so far I did not find the time to implement these backends. It also seems there is some fragmentation of linear algebra routines for generic numbers / BigFloat across different packages.

Edit on this: GenericSVD is deprecated, GenericLinearAlgebra implements all the necessary features I believe?
