I do expect a considerable amount of documents. I at least have quite
some of them, and my guess is there are many more.

And, it provided a programmable finite state automaton at the input side
of TeX (the OTP - Omega Translation Process), which allows to treat
complicated scripts like Tibetan or Devanagari without a preprocessor.

I still consider it the superior solution, at least concerning Tibetan:
Both luatex and xetex fail badly with Tibetan scripts and are
practically unusable for real typesetting.
