yes, but I think it warrants further study. some GI issues are related to one or just a few bacterial strains being unbalanced, so it could be extremely useful in treating gut microbiome imbalances to know which strains are negatively impacted by specific sweeteners
conversely if we found any specific sweetener to have a bacteriostatic or bactericidal effect on a strain that is pathological when overly populated (e.g. H. pylori), that could be a super easy way for some people to prevent chronic flare-ups
