It is, but the the average user's perspective is not that they'll set up an IRC bouncer (which odds are high they don't even know exists) so they can have message permanence and cross-device sharing.
Instead they'll say that IRC has no history / offline support (which is, technically, true) and will use discord because it does.
What we learned from the Freenode implosion is that for most IRC users the concept of different networks was entirely alien. IRC was Freenode for those people.
It doesn't help that the authentication story for IRC is a bloody mess. In Discord, I have one account and can join any server^Wguild and have a different nick in each (and the nicks support unicode, and emoji). If I want to have different nicks on different channels on an IRC network I need 2 separate logins.
I’m sorry that the new update for quassel and quasseldroid is taking so long :(
