Is there any value in taking a reading with the hydrometer after 3-4 weeks of a new brew in the bottle? Does the priming sugar's reactivation of the yeast make much of a difference?
 
Technically, you'd need to take a gravity reading after adding priming sugar, then again after it's bottle conditioned to get proper accuracy.

However, we're dealing with relatively small amounts.

Without both readings, you can only calculate anyway. Setting that aside, sugar brews out completely, so throwing 4 ounces corn sugar in 5 gallons through a calculator says .21% ABV, or relatively little difference overall.

What you'd see with your hydrometer is roughly a 1 to 2 point change, and over 5 gallons you'd come up with a range of .2 to .4% change in the ABV.

Too small to dink with too much or worry about, from a practical standpoint.

yes. Besides what were you planning on doing, you'd have to degass the sample to remove the co2 to take an accurate reading anyway. There's really no point in doing it.
