This can only be answered by each person based on the type of work they do, and perhaps none of us really know if any of our images will have any value to anyone in the distant future. But for the past 40 years I have seen many people pay large sums of money to get old photographs restored, and over the past 10 years or so the desire to fix color fading issues has become more common.
Fading is not the number one concern when evaluating print longevity, as physical damage is far more likely to be the end of a print before it seriously fades, but if the image has value and is cared for then it seems prudent to make sure what you do now doesn’t limit the ability of the image to last into the future if you feel there is a possibility someone will still value it.
Interestingly enough, I think portrait and people photographers should have the most concern for this, as those are the images which probably have the greatest likelihood of maintaining some value to future generations, yet many of them seem content with processes such as c prints or dye based prints.
