Reading the posts over the years, I've read of tents that have been rolled (or folded or stuffed) that lasted for years (actually some even a decade or more)! Just as importantly, I've also read of tents that were ruined (usually delaminated) in just a short period because of moisture/heat/light -- regardless of whether they were rolled, folded, or stuffed.
I can see how folding along the same crease lines will damage the fabric eventually -- but as you mentioned, perhaps more in "antiques".
So what I'm saying is that just like how some people state that tent pole sleeves are stronger than tent pole clips -- there may well be a theory behind it -- but this theoretical difference is either so minute or takes so long to manifest itself that it really doesn't matter in the practical sense.
At the end of the day, what determines whether I fold/roll or simply stuff is the shape of the tent and fly themselves. A Rainbow tent just lends itself to folding/rolling. OTOH, the very odd shape Big Agnes Seedhouse 2 fly just "begs" to be stuffed instead. YMMV, of course.
