They could be doing their job but not be the central onboarding path.Even if it's one part of a multipath strategy they seem key (and thus are doing their job) since WotC has released 3 starter sets in the span of it's lifetime. If they weren't doing their job why continue to invest in not only selling them but evolving them?
A 32 page rulebook and adventure seems a small easy investment to develop.
They could be comparatively small print runs to meet the comparatively smaller demand for them.
Having new sets instead of reprinting old ones means an opportunity for marketing new products and perhaps double dipping on existing customers who already have one.
New sets can tie into hot properties as they did with Stranger Things (which also presents a double dipping opportunity).
Without more data the existence of multiple 5e starter sets tells us they have thought it was worth doing multiple times, but not much more.
