I don't think the lower end pi's are perfected (or anywhere near) either. The actual products are pretty good, but all the peripherals are pretty expensive and make the value a lot worse. A Rhasberry Pi zero only costs $15, but the case and SD cost $5 each, so the most basic config ends up costing way more than it should.
If they wanted to expand their offerings, IMO they should have focused on delivering sensible bundles (e.g. Pi+SD+case+power adapter) that aren't huge markups over the board alone (or maybe making variants custom tailored to specific use cases, e.g. a Pi-zero with emmc storage and insulated so that it doesn't need a case for long term use).

So Pi is really filling a niche where you want form-factor, perf, and power consumption - but not necessarily price. This keyboard is firmly in that niche.
