Hi Kay,
maybe we should make the deprecation process a bit gentler: instead of
ripping out the functionality in one step, instead just deprecate the
functions, and allow people to use them, with the caveat that launching
a namespace and creating devices in it will break this functionality.
Then after a few releases, actually remove the functionality. Not everyone
uses namespaces, and that'd be a nod towards those poeple. Would
that be possible?
