It seems odd that Apple could release an update that breaks common software, and not go to the trouble of at least contacting the developers of the software and discussing the issue.

Before I left Apple ~10y ago, it was pretty common to drop linked-on-or-after hacks into AppKit and UIKit to keep popular software chugging along. Assuming they're still doing that sort of thing, this was either missed or deemed not high-enough priority to add such a check (or maybe one was added, and the only reason this issue has been noticed is because Electron and Electron apps are now being built against the macOS 26 SDK).
