Yes I was because that is the hardest case. In hindsight it is also the
most useless. If you see a billboard device you can still react.
But the point also applies to all "switchable" features,
most importantly PD.
I usually want to charge my phone if it is connected, but not
e.g. if my battery is at less than 60%. Such things belong
to user space and should ideally be setable before anything is
plugged in.
