The listing of "10 arrows" rather than "quiver of arrows" has no inherent bearing on whether or not each arrow fired is meant to be removed from play.
I say that because the function of saying "10 arrows" rather than "quiver of arrows" is to set a clear limit how many Strikes you can make with your bow before your quiver runs empty and you need to switch weapons, improvise, or recover some ammunition mid-battle - and it doesn't have to be anything more than that.
I will add to that that mundane ammunition being recoverable, barring specific exception such as leaving the field of battle before having the opportunity to recover fired ammo or the like, is a reduction in book-keeping - as is having magical ammunition get fully used up, rather than only the magic being used up and the ammunition becoming mundane.
And lastly, a hypothesis: the thought that mundane ammunition is used up because magical ammunition is stated as being used up is coming from a thought process that expects the new edition to behave like the old edition unless a specific piece of text says "this is different than it used to be" more so than a reading of the text in the new rules by itself as a stand-alone entity saying anything directly related to the idea.
I like thenobledrake's interpretation and think it should be added as an errata, namely:
"All non-magic ammunition can be recovered from the battlefield after 10 minutes of searching."
A nice simple single sentence to clear up the misunderstanding, minimise book keeping for generally trifling amounts of money and make most people happy :)
