No - There's nothing wrong with it. But they have to continue to release builds at least or operating systems may not support it without using a VM and an older version of the OS.
Sublime Text 3 is still in beta. It doesn't need a new release but it's been 6 months since the last build, so if it's feature-complete it should be reflected with a major, stable 3.0 release.
That's my main concern at the moment.
