Just tested with bob functions v1.1.4 and this mod v4.1.5 (currently latest update) and the inserters still appear in the tech tree and crafting menu. You may be running bobs adjustable inserters, which is not supported by this mod (I currently have all inserter changes disabled if it detects bobs adjustable inserters). You can check this by starting a new game, and if a message appears in the lower-left corner, then that would be the issue.
Although now that you mention it, I implemented this change before adjustable inserters became a separate mod, and before Factorio allowed for explicit mod incompatibilities. I probably could just force the hard incompatibility now, instead of the soft one that is currently in-place.
