This looks like a nice improvement and should make it easier to add new bundles in the future. You addressed the previous issue we found (as mentioned by @SamTebbs33) and I couldn't spot any more issues, so I'm happy to accept it.

It would also be nice for this to land so we can rebase 144908, which @SamTebbs33 told me would make some of the changes in that PR a bit simpler.

In any case, LGTM!
