What sort of documentation is available for \pdfstrcmp? I confess that I have
never heard of this toolset.

At present there is not too much of an issue: we don't have any working
functionality for LaTeX3 where this question really shows up. This may change
once we have some font stuff. (As I said, I have some ideas in this area, which
include 'shameless rip-off fontspec'.)
There is quite a large body of stuff which doesn't really need LuaTeX: stuff in
western European languages using fonts already available to TeX. I suspect that
forcing this subset of work to drop pdfTeX, which is quite capable of doing the
job, might be consider a bit 'over the top'.
As I said earlier, we decided to require \pdfstrcmp after some applications came
up where the alternatives were a bad idea (difference in expandability with
different supported engines). So this might change as we develop more code. I
can only comment on what we have now, where there is no strong case for dropping
support for pdfTeX. (Indeed, almost all of the day-to-day testing I do uses
pdfTeX as it remains my default engine. LuaTeX is a lot slower, I'm afraid,
quite apart from questions about bugs introduced by the ongoing changes.)
