I'm guessing you mean "... used a static build of Qt." since they're the
only ones (b) would change, if made the default. Otherwise, please
explain how namespaced builds get broken by this - if they were static
before, then this just makes them the default, so no change; if they
weren't static, this change won't affect them.
I can believe static-built apps are common; and I guess apps using them
would need to make source changes in order to switch to their namespaced
form, or override the default of them being namespaced. What other
problem(s) had you in mind ?
