I think it's awesome that the Trinity team takes advantage of the Freedom the community offers to keep something alive which many consider dead. Maybe Bruce could've mentioned the possible security risks of running such a huge, old codebase with so few maintainers, but aside from that I think Trinity is fine.
I am unsure about their effort to port Trinity to Qt4 - I fear they end up rewriting so much (eg to model-view etc) that it is not different from what mainstream KDE did in this regard. But maybe they decide to port it to Qt5 and QML some day, that'd be interesting :D
In any case, I'm happy packages are available for a number of distro's (which btw includes openSUSE) so people can try it out. I think many will notice their fond memories of KDE3 might be a bit over-stated when faced with reality, but for some use cases it'll do fine.
