Deeper 2026 evidence shows the dominant QR/phone feedback case is 'very high' feasibility and a days-long mainstream build, where the prior score of 3 under-weighted how trivial the software is and over-weighted the hardware slice; this lifts it to 4 and aligns it with its three near-identical feedback peers.

Score movements
The prior score of 3 under-credited an already-mainstream buildable core; deeper research on OSS engine production adoption (numerous named enterprise references) plus AI now authoring migrations puts the core past the 80% mainstream-self-build bar.
Better research on OSS backend production scale — Jaeger at Ticketmaster, Tempo at Houzz, SigNoz/ClickHouse at Dream11 (357 TB spans/month self-managed) — showed the core is a mainstream 80%+ self-build, above the prior score of 3.
Deeper research on OSS production scale — Dropbox running company-wide Loki after retiring its legacy system, Qonto, Deutsche Telekom on Graylog — showed the core is a mainstream 80%+ self-build, above the prior score of 3.
Moved 3->4 because this pass surfaced Discourse's mature, named production references (OpenAI, GitLab, UiPath, Elastic, Docker) covering 80%+ of the community core — a mainstream self-host reality the prior score under-weighted; no market event, just deeper evidence.
Research corrected the prior 'not buildable' read: agency-facing layers are buildable against public RMA data; only the regulated core requires an AIP.
Prior 3 predated the maturity of Scalar's OSS interactive playground and OpenAPI plugins; the docs-plus-reference-plus-playground core is now self-hostable at scale.
Prior 3 understated OSS maturity; Weblate self-hosts ~90-95% of a conventional TMS and the react-i18next + OSS + AI stack covers 80-95% of a software team's needs in production.
