I'm not gonna be out here like "yes let's make all raids mandatory this is great" - no. But in this particular case, for this particular raid, it just makes sense from a storytelling perspective.
ShB could not have happened without the WoL specifically doing those quests. It's just a matter of whether it's in their past or their future at the time - although at whatever point you actually do CT, it happens in post-ARR (as indicated by Nero being straight from his defeat at the Praetorium, plus the overall way sidequests are handled) and just slots into place in the timeline once it's done. It never happens after ShB unless you haven't done it at the time of playing ShB.
Technically the events of all three Ironworks raid series are necessary to set up the time travel plot - CT, Alexander and Omega - but again, all three are handwaved to have happened at some point after ShB if you haven't done them yet. The timeline is wonky if you try to make this actually make sense, but you don't need to - they happen at the time in the plot when the raids were released, regardless of when you play them. If you played the Alexander quests right now, Y'shtola will be "back in the Source" because it's her Lv60 post-HW self and not her at the current point in time and story.
