For example, let's say we want to add Qt::inline Literals::inline OtherDomain::_s, what should be the "q"-prefixed version of it? We can name it to something like _qXs, where X is some domain specific letter, but it will require even more typing, and make the name inconsistent with Qt::inline Literals::inline OtherDomain::_s.

I'm not sure how this work: unless the new _s takes another kind input 
(e.g. number literals), you can't add it no matter what, as users under 
"using namespace Qt;" would then get a conflict...?

Sure thing, that's why I'm OK at deprecating one of the two.
