I'll count the approving comments in the thread above and lack of further objections as good enough approvals to merge this patch. Primarily so that the modified strings can make it into 6.1 before it gets branched, and the first commit ("Hide profile load/unload fields if battery profiles are absent") can get cherry-picked into Plasma/6.0 before 6.0.5 gets tagged.
Shout at me if that's not what you meant and I should get a more formal approval.
