Frequency & alternatives
Recent records to compare: “Ask HN: Do you still enjoy coding in C++?” (Hacker News, Nov 9, 2026); “[问与答] vibe coding 时代，前后端分离还有必要吗?” (V2EX, Nov 9, 2026). Shared themes are navigation hints; they have not been verified as the same need or independent corroboration.
Demand hypothesis
Treat the reported task or obstacle as an interview lead. A feature request, complaint or search for alternatives does not by itself identify a budget owner or willingness to pay.
Commercial evidence gaps
Missing evidence: distinct affected users, repeated occasions, current workaround, measured time or money cost, purchasing authority and a response to a concrete offer.
Validation decision
Group original reports by the same task and deduplicate authors and reposts. Ask how the task is handled today and what it costs; test a defined offer before claiming paid demand.
