That’s unfortunate and self defeating IMO. Sutta Central meta data would show the info for where to get the full book, and not making the individual suttas available to compare with other existing translations easily in suttacentral, you’re just relegating yourself to obscurity. When one can easily see Sujato’s forthcoming Therigatha translations, Thanissaro’s partial translations, PTS and other translators on SC easily and instantly in one centralized place, why would one want to go through the trouble of digging up other translations?
For the same reason, I’ve always been interested in reading more of Piya Tan’s translations and essays, but by only having it in non unicode, and in PDF, guess what? The inconvenience of that nonstandard format, and not having it easily available on SC, means I ended up not reading it.
