I went the minimal-effort way since it doesn't matter much now when we only
check for two device types. And the better approach could have been done as
another patch in the future.

But since you already have it, it'd be better to push that first. You can also
take just the most important part of it and do the rest in a separate patch
later to minimize it's time consumption now.
