I think we live in a day and age when much of what used to be seen as clear-cut revelation now is interpreted as non-revelation. I think we have seen what happens when previous leaders interpreted their own feelings and beliefs as ordained of God (e.g., the Priesthood ban) - and so current leaders are careful now only to attribute "thus saith the Lord" to things where they are certain it has been communicated through extraordinary means.
I'm OK with that - since many people chafe at being told specifically what to think and believe. It's a two-edged sword - and I'm not sure anyone really wants the President of the Church and the apostles laying out lots of things we simply MUST believe as coming straight from the mouth of God in a way that closes the discussion and says, essentially, "Shut up and accept this." I believe most members don't want a return to the Law of Moses and its myriad regulations, restrictions and legalism.
It's one thing to be able to say, "Our leaders are fallible, and it's up to us to ponder and pray about what their words mean to us personally;" it's a completely different thing to say, "Please tell us, 'Thus saith the Lord' and take away our need to find individual meaning and divine connection for ourselves."
I also think there is validity to the scarcity of "new stuff" between Nephi and Alma in the Book of Mormon - and the blunt statements of the leaders at the end of the small plates of Nephi that say, essentially, "I know of nothing new, so I'm not going to clutter the plates with my own ramblings." The Church makes changes (and sometimes pretty radical changes) on a regular basis in both what it teaches and what it does. I'm fine with attributing that to revelation - which I define as "insight from God" received in some way.
Given that definition, I'm fine with revelation being the result of long-time dedication to striving to understand and come closer to God - even when it happens through what we might naturally consider to be "normal" means, and even when it doesn't appear to be revelatory in nature.
