I use a simple arrow fletching mod I made for myself in the Creation Kit in a half an hour so it's very easy to add this type of functionality into the game, the question is if they want to add it in. The game as released was obviously intended to have the high-end arrows be fairly to very rare so they perhaps didn't originally intend for you to able to craft them by design rather than as a simple oversight.
I use hawk feathers, hagraven feathers and quills as part of my feather requirement in my mod if you're at all curious btw. They're uncommon but certainly not rare, especially if you go into certain caves or alchemy shops with the intention of collecting those types of feathers for use in arrow crafting as opposed to alchemy as they're usually used. Or just head to Solitude and practice your aim, heh.

Add in some ingots and firewood and done - simple arrow fletching, adds a lot to my archer characters to be able to use otherwise useless ignots and mining opportunities to create useful ammo for my bows. We'll just have to wait and see if they are going to add it in officially in the future.
