[Development] QUIP 14: The module life-cycle and criteria for transitions

[Edward Welbourne]

Hi all,

Back in 12 January 2017, when we were discussing Qt Remotes Object as a
Tech Preview for Qt 5.9, Lars set out [0] some criteria for modules to
enter tech preview.  It occurred to me that this was worth turning into
a QUIP, along with criteria for the other transitions of a module's
life-cycle.  I've now pushed a first draft of that for review [1].

* [1] https://codereview.qt-project.org/246320

There are some big TODOs that require discussion on this mailing list.
I'll endeavour to formulate whatever consensus I hear in that QUIP.
What are (or should be) the criteria for transitions to the maintained,
obsolete and deprecated states ?
