(1) Are you only worried about this insofar as spellcasters are concerned? You haven't mentioned anyone other than wizards and clerics.
It doesn't matter if you are martial, arcane, divine, primal, elemental, shadow, ki or whatever other power sources they are going to come up with. Characters are limited by the at-wills that they are tied to at character creation. This makes having characters that do not fit the mold of those at-wills outside of RAW and a limitation of the game system. So no I don't really care if they are martial, martial characters should do their heavy hits less often too, it doesn't matter what power source you are. Why have a special attack at will is not very special. Not to mention when it straight jackets your character creation. When I look at a class that I want to play in 4e I look first to its at-wills and class features and determine how I can maximize the effects of those. If one of them says you have to use a certain weapon or cannot use a certain weapon those are undue character creation rules that I don't prefer. You may prefer those limitation, I like options.
(2) What options do at-wills prevent? What archetypes are blocked by 4e that are also enabled by the system you're proposing? You mentioned the elf archer cleric, but it's pretty clear that this build works fine, at least IMHO. Give me some more examples.
Well the cleric with a bow is just an example. But essentially any character whose at-will powers are better than simply making a character with a sword or whatever weapon the player wants. Not to mention the flash bang of certain at-wills make the game feel a lot more magical as Cadfan illustrated.
(3) Why is it preferable to eliminate at-wills entirely, as opposed to increasing the number of encounter powers and leaving at-wills as-is?
This is another solution. A pretty good one to boot. It would give some more variety to players out of the starting gates. It does nothing for the endless magical effects (or ninja effects for martial) stuff though.
