I suspect that the "large-file-threshold" and the "long-line-threshold"
can both be kept small enough that they accommodate the case of Eli (or
myself) running a slow build of Emacs on a slowish machine without
significantly affecting those who could live with larger thresholds.

IOW, I think this part of your discussion should wait to see what actual
thresholds seem to work well in practice because it may prove to be
a non-problem.
