Hi Richard,

I can only provide an opinion, it is not my place to make decisions.

I would like to see qbs as a supported build system in Creator for as long as it
does not cause too much hassle to do so. That is no different to any of the
other plugins Creator has.

Keep it supported: Qbs needs to build with a Qt version supported by Qt Creator.

Keep it enabled in the binary packages: Qbs needs to build with the Qt version
used by the binary packages.

I do not know more about the timeline for Qt 6 than you do.

We will build Qt Creator with Qt 6 ASAP. It is a testbed and bug-detector for Qt
after all.

But as Andre already stated: We will also keep Qt 5 compatibility for as long as
that is practical.
