If you move sites to WA, do you also move registering their domain names?

For many years, I was careful to register my domain names at a different place than where the sites themselves were hosted. This was based on the conventional wisdom that you couldn't trust the webhosts with your domain names in case they had technical problems. Or ethical problems, for that matter. A healthy dose of paranoia had people keeping domain names and sites apart. I'm sure many of you remember this and maybe still do this.
Now I am moving all my sites gradually over to WA hosting, and it's a good time to question conventional wisdom. (Umm, *anytime* is a good time to question conventional wisdom, I suppose.)
SO here's my question to anyone who has already moved sites to WA or plans to: Where are you going to register the domains you own?
It's a practical question as well as a theoretical one. My domains have been registered at a well-known and well-respected registrar, name dot com. But it doesn't realize that the nameservers WA uses are real. That's where it sits at the moment, as I have 2 sites that I have here in siterubix, ready to move to their own spots. I've been in touch with WA tech support and as usual they are very helpful, but right now this is more a tactics question than a how-to.
I feel differently about WA than about the several hosting companies I've used, and it would be easiest to have everything here.Easy isn'tr always best.
What have you done, or what do you plan to do?
No problem with transfer to WA hosting!
