Anton,
I pushed a fix

in branch hzhang/fix-superlu_dist-reuse-factornumeric.
Can you give it a try to see if it works?
I do not have an example which produces your problem.
In your email, you asked "Setting Options.Fact = DOFACT for all
factorizations is currently impossible via PETSc interface.
The user is expected to choose some kind of reuse model.
If you could add it, I (and other users probably too) would really
appreciate that."
We do not allow user set superlu' Options.Fact = DOFACT. If user
changes matrix structure, then user must call
KSPSetOperators() -> call symbolic matrix factorization again, in
which we set Options.Fact = DOFACT.
