Sorry, you're right. But the legacy (non entry-point) scripts are certainly fragile, and I'd recommend avoiding them. Even for actual scripts, and *certainly* as a hack to get things in the "Scripts" directory...
Note that PEP 459 currently proposes preserving this capability as "python.commands.prebuilt", so I personally consider it reasonable as a way of packaging arbitrary executables and non-entry-point based scripts.
Existing code tends to try to rewrite shebang lines on scripts. And maybe on Unix add the executable bit. The wheel spec (installing a wheel, the "Spread" step, item c) actually requires that script rewriting is done, so in theory that makes the scripts subdirectory in a wheel unsuitable. In practice of course, DLLs will be fine as they don't start with #!python. The "python.commands.prebuilt" spec doesn't say whether #! rewrites are done. If they are, they have the same issue as scripts. If they aren't, the current wheel spec doesn't offer an appropriate area to put them. Basically, it needs a wheel spec update to have an area which holds files that are copied unchanged to the destination Scripts folder. But this is entirely standards-style nitpicking. The existing scripts support is fine for DLLs, and will work as expected for every practical purpose. That's why I called it a "hack" - it works, but it's unofficial. Paul
