If johnstone can be retroactively nerfed, the likelihood of the above explanation with technical issues, is weak or being addressed only to those items that actually benefit from previous versions.
That is true, normal legendaries can indeed be changed retroactively (see Rimeheart and Furnace a long time ago). It's *different* from a technical viewpoint, but not impossible, so my "the technology isn't there yet" is more to be taken as a meme. After re-reading Nevalistis' post I actually realized that it leaves some room for interpretation, so maybe it's just also a deliberate decision to not tamper with existing items (anyone who has ever done coding knows that changing one variable can cause 10 others to break). Or maybe there's something in the implementation that truly makes certain changes more difficult (some of the items were semi-retroactively changed, like Dead Man's Legacy which looks like the new version but just with a lower roll).
Basically, they were discussing this internally but decided to maintain their current approach (retroactively buff sets, but not legendaries). It's safe to say that it's mainly because of technical reasons, and whether that's normal legendaries, ancients, or primals, makes no difference - "the technology just isn't there yet".
For me personally, as someone who has never been a "season pushing player" but likes the continuity of non-season, it gives me new goals to farm. I've already gambled/cubed the new DH weapons yesterday (speedfarming GR90s with Multishot is just SO MUCH FUN) and now I've got some things to do on other classes as well. To be honest, I always complain about the loot hunt being so quickly over, at least compared to D2, so it isn't all that bad in my opinion. Also let's be clear - the list of items you have to replace isn't that long, it's about 5 per class and usually 1-2 per build or so. Some builds even didn't get any changes (like MH wizards) and some got changed a bit more (like the new SWK mechanics or the 3 items we need to re-acquire or UE MS DH). It's not like you're salvaging your entire stash.

There was a long debate about this on the official forums.
