Compat analysis: Analyzed ~2,200 files across JavaScript and TypeScript on 
GitHub for both deleteWordBackward and deleteWordForward usage, with full 
source context.

Change scope: In Chromium only, when a non-collapsed selection exists and 
the user presses Ctrl+Backspace/Delete, inputType changes from 
deleteWordBackward/Forward to deleteContentBackward/Forward. Caret behavior 
is unchanged.

Results: Of ~2,200 files, 10 unique repos (after deduplicating forks) check 
deleteWord* without also handling deleteContent*. Of those:

   - 3 are typing test apps where the trigger scenario (select text → 
   Ctrl+Backspace) doesn't arise in normal use
   - 5 have native browser fallback — selected text still gets deleted, 
   just through the native path
   - 2 are niche tools (academic NLP tool, personal terminal emulator) with 
   a minor behavior difference

Major frameworks (CKEditor, Lexical, Slate, Odoo, monkeytype, 
GNOME/evolution) all handle this correctly already. No major websites or 
widely-used libraries are affected.

Interestingly, I noticed that the shipped feature already has the runtime 
flag enabled (stable since *M145*), and there have been no bugs or 
regressions filed against it, which further confirms that the change hasn't 
caused any meaningful breakage.

The runtime flag (InputEventsDeleteNonCollapsedSelection) remains available 
as a kill-switch if needed.
