Yep, it was part of the reason I caved in and bought a completely new bike. As much as I hate being a lackey to the marketing men who have made an infinite number of minuscule ‘improvements’, nothing on my old bike was upgradeable.
For an average trail/mountain biker
While 1 1/8″ straight used to be gnarly enough, now I need tapered.
While 20 mm maxle used to be lightweight enough, now I need 15 mm.
While HT2 outboard bearings used to be stiff enough, now I need press-fit.
While a QR rear wheel used to be stiff enough, now I need 13somethign mm bolt-through.
While wheels used to be round and approx 26″ in diameter, now they don’t roll well enough and I need a 29er or 650b.
