Conceptually, perhaps both this and MTP should go under the top-level Devices category in the Places panel instead? Appearing on-demand, if applicable. The logic would be that users see these features as device access methods, not network protocols

Both KDE Connect devices and MTP devices plugged in via USB show up in Dolphin's Devices places category already, don't they?

Oh, if that's the case, then great! (I don't have an Android phone I can use to test either MTP or KDE Connect).

Why do we need links in remote:/, then?

+1 otherwise

(and imho MTP doesn't really belong to "Network").

So, the consensus was to instead drop MTP as neither KDE Connect nor MTP really qualify as "network locations". Moreover, both of them show up in Dolphin's Places panel anyway. Thoughts?

That would make sense to me, yeah.
