No it wasn't. Oblivion even made NPCs in the Arcane University sit in the public area when you had related quests where those NPCs would normally be unaccessible. You have to join the Arcane University for the amulet quest in skyrim, I believe the step for the main quest might be skip-able where you go to the college but I'm not certain since I haven't tried. The NPC who you speak to normally is in the college, and given how the quest in the thieves guild makes the related NPC go to the local Inn I wonder why there is this design flaw, why can't the other NPCs go to the inn as well? And why is the same dungeon used for two completely unrelated quests but entirely blocked off by one of them.
I also find it annoying that some shouts are blocked off by guild quest lines as well, I mean the main quest line makes sense that it'd hold some of them back but that other shouts are blocked off is annoying. It'd by like Oblivion making you have to join the Fighter's guild to learn the water-breathing spell... or joining the thieves guild to learn fortify attribute.
