Free trials generate the stars, but charging both monthly and per-call fees filters for experimenters over builders. People explore but don't commit to production. Prob why most installs end up abandoned or as toy connectors nobody ships.
Delegation heuristics are prob the tricky bit. Codebase investigator is obviously a win, but routing decisions get interesting when you're weighing cost against latency for different task types. Multi-model setups will just be how this works once people figure out the right handoff rules.
