That was just because my original idea was to first reimplement TeX in Scheme, and then investigate how I could extend it, in a convenient programming environment, but so that the new implementation remains compatible with the normal TeX (if possible, maybe in an "old TeX mode"). One of the extensions I had in mind was use of a constraint language embedded in Scheme (like the port of Steele's thesis or maybe a future port of Siskind's and McAllester's Screamer) to improve TeX's layout capabilities (e.g., for a magazine, to put boxes across pages, wherever they would fit nicely). Then I thought it might be better to first look at DSSSL and see if something like this extension could be expressed in it (I still have to figure that out). Even if not, it could be interesting to make a back-end that would generate Scheme code that calls some typesetting primitives of the new, extended TeX implementation. Altogether, TeX is the only reason for DVI. However, I just printed out the PDF 1.2 specification from the web. Who knows what I might come up with next :) Anyway, I will probably think about this in the following months, and maybe start programming in my spare time if I get a clear enough picture of the whole thing.
