When they figure out ways to monetize qol then we will see improvements. Just like the old 2v2 mode, was a very popular mode then they changed it to HS and only giving a handful of free battles then you could buy more plays with acoins... didn't work out for them so they completely ruined the mode and walked away from it. Once they figure out how to make money from it, we will see something that the community will mostly hate.
It looks like the OP has only mentioned clan improvements specifically, but there's also the complaint about general QOL. It is worth noting that there have been QOL updates. Off the top of my head, I can say the new tournaments format is a huge QOL update for a number of reasons, not least of which is quality of real life :-). (Not to say it is perfect.. the tourny rank based matchmaking is of course problematic.) Another is the frequent and high value ECRs. A slightly older but still good one is making all 3 hangars available upfront. It's possible there are more.
They have made and continue to make mistakes (intentionally or otherwise), but on the flip side we can't say that QOL improvements are not happening. Credit where it is due.
