> Also, the number of addons you want to preinstall has to be quite small - past a certain limit, it's too much clutter in the UI, as you correctly said (and indeed the number is very tiny: Pocket, Hello, and Search if you count that).
I think that the wording here is important: Pocket is not an add-on, at least in the sense that I understand it: when I go to Tools > Add-ons, nothing there allows me to disable or remove it. (I can't find it now, but I thought that one used to be able to manage search providers in a similar window.) Add-ons are by their nature trivial to disable or remove, and a solution involving going into about:config, where the user is explicitly warned of the dangers—in language far more frightening to a non-techie than any opt-in could be—is not trivial at all.
That's true. As mburns commented above, it looks like the goal is in fact to do the extra work in order to turn Pocket into an addon, for the reasons you mention.
