That doesn't change the difference between effective and toxic doses, it changes the potential scale of off-by-one user error. If 20 milligrams is delivered in 1 tablet, then 3 tablets is the toxic dose. If 20 milligrams is delivered in 5 tablets, then 15 is the toxic dose. A single daily tablet is far superior to multiple daily tablets in terms of patient adherence and hence disease management.
Can you name specific examples where the number of pills/capsules/tablets has been increased to improve drug safety? Increased pill counts historically reduces patient adherence, which worses disease management. This is just the first example I found which measured it: https://pubmed.ncbi.nlm.nih.gov/31298592/ This review explicitly states it in the abstract even: https://pubmed.ncbi.nlm.nih.gov/30561486/
