Typically, such proposals have some sort of "active" element in order to maintain stability, since SEL1 is only a meta-region of quasi-stability. A couple of the Lagrange points have true stability, but they would not be in a location optimal to function as a geoengineering proposal.
Alternatively, that lack of true stability is pointed to as a reason why, if space-based methods did not work for whatever reason and/or had unintended effects, they could simply be allowed to float off into outer space.
