They're not "removing" it, they're just not continuing the artifact weapons for BfA. You'll still have your artifact weapon that you'll be able to use on Timewalking dungeons.
EDIT: also, if the "artifact weapon" feature remained for BfA, there are several issues with that. Some of them being: if the current artifact weapons continued, how to expand on their functionality? All the traits would be already unlocked, and you'd take several months to get a single new artifact level. Add more traits? That would cause inevitable bloat. No, artifact weapons should be "retired".
