Those are not superficial things, countless builds could be made around those hypothetically cut things alone.
What about the countless builds that could be built around different perk combinations? Is it simplified because the content you used to base a character around has been (supposedly) replaced by a much more personal and expansive system?
Besides, with the way you "leveled" attributes in Morrowind and Oblivion, it was very hard to enjoy a character while trying to build them around something like Agility or Speed. If you were really serious about it, you had to keep track of
when you would level and
what you were leveling. To guarantee five attribute multipliers, sometimes it was necessary to make an important skill for the build a minor just to ensure it could be leveled enough without leveling the whole player. The micro-managing "play to win or be handicapped" leveling system was always my first priority when it came to mods (
love GCD and nGCD). If Skyrim would keep the attributes and just alter the way they're leveled I'd be more than happy, but I'm looking forward to seeing the perks in action. Only then will anyone really know what we gain and what we lose between systems.
All that said, I think Bethesda changed too much on us too fast. Attributes alongside perks would have been great, and save the attribute removal for TES VI. If there is one, of course.
