I doubt they'll do it though, but one can hope..
Blizzard wants a more live community. CRZ is solving 1/2 of that issue. The other half is that when you see other players, they are competition. You don't want them to be there. It's been like this for so long that no one can see that this is the real issue. No CRZ will simply mean for some places, on some servers you will basically be playing a single player game.
The better solution is to make it so that the effect of other players being in the same place as you has a more positive effect than negative. Although I can think of a dozen ways right now to make this possible, they will all have side effects that could make things worse.
Not all servers are merged, Hellscream EU the server I played most of my time on is completely dead and has been for a long time, no sign of it being merged either.

I noticed something yesterday too. I was on one of my alt servers (Zangarmarsh), and one of the realms that it's connected to with CRZ was down, which meant no resources, NPCs, or mobs out in the world. I couldn't do anything on it other than sit in Org, which is fucked up to be honest. Those things should be visible regardless of what realms are up or down for maintenance.
They are not the same thing in terms of scope and commitment. Connected realms probably require some infrastructure changes to make the merge more efficient - i.e., not having all the problems of transient connected realms - but at the cost of making the merge permanent. Blizzard was probably not willing, from a business or technical standpoint, to make the leap into permanent live server merges until they had some empirical data to look at.
Why do people want empty zones? Fine, your 47th alt might not give a damn about leveling and is just rushing through.
That is not the case for everyone.
CRZ was dumb to begin with, and that's one of the only changes Blizzard has ever made to WoW that I'll say that about. It never should have been in the game and with realm mergers it's about time to get rid of it.
Phasing is even worse than CRZ if you ask me. Try flying with a 2-seater over phased areas. That's pain.
CRZ has made levelling an absolute pain. Ever tried doing the starting barrens quests recently? Takes hours because the mobs are camped. Absolutely no point whatsoever in filling the world up when the world isn't capable of dealing with the amount of players required.
It makes rare hunting so much worse and I've personally (as someone who's levelled by questing a lot) seen absolutely 0 benefit to myself as a customer and those around me that CRZ has given. Never once have I thought "oh that will work because of CRZ" or "CRZ helps there". It has been solely a detriment to gameplay since it's implementation, for me.
This has turned nearly every quest I ran into doing 58-68 that involved killing a named mob into a 5-10 minute wait for the respawn while spamming AOE mindlessly hoping you tags the mob over the 5-6 other faction players in the area doing the same. I can't see many new players wanting to deal with that more than once let alone for 10 solid levels.
