If we take the files bundled with Emacs and look at how many ELPA packages they would turn into, we'd end up with a load path that has more than 200 elements. FWIW, I've always been wary of having "one dir per package" because of the performance impact of having a thousand directories in load-path. Lookup in a large directory is easily optimized to O(log N) or something like that, but a search along load-path won't be similarly optimized by the kernel. [ In `install.el` (an old package that predates package.el), I installed all single-file packages into a shared directory specifically for that reason. ] This is not based on actual experience, tho, so maybe I'm worrying about nothing.
