I see this as the best option then, ignoring quests in your journal. If you don't like a quest being there, you can hide it. If you decide to do it later on, you can unhide it. If you don't want to ever do it, leave it hidden forever.

That would be a step up, but I still find it unnecessary to dump quests into my quests log that I know I'm never going to do. Oblivion never had this problem, and there was no issue with quest entries getting stuck in your journal... it was not a problem to find quests or anything, either. It's like Skyrim needs to make sure you can't ever forget about anything the that may be possibly related to a quest, just in case. Immediately enter a town -> automatic scripted event -> quest added. Walk to close to someone -> scripted pvssyr -> quest added. Pick up an item -> quest added (and you can't get rid of the item from then on).
It's very presumptive in assuming that I care about these things and want them in my quest log. If I cared, I'd ask about it, and if I didn't like it, I'd say no to avoid taking the quest. Clean and easy. But in Skyrim, it's added automatically, and even in the rare cases you have the opportunity to say "no", it's treated as "maybe later" and leaves the quest entry active... just in case. Your inventory also gets cluttered with quest items for quests you will never do. I'm a grown person, I know when I don't want to do something.
