On the tool changes, I'd prefer --move and --un-move as pair over --move and --clear ("clear" is less expressive IMHO).
On "--reprobe -> --refresh": Why not simply "--probe"?
On "--crm_xml -> --xml-text": Why not simply "--xml" (XML IS text)?

> Pacemaker 2.0 will be a major update whose main goal is to remove
> support for deprecated, legacy syntax, in order to make the code base
> more maintainable into the future. There will also be some changes to
> default configuration behavior, and the command-line tools.
> I'm hoping to release the first release candidate in the next couple of
> weeks. We'll have a longer than usual rc phase to allow for plenty of
> testing.
> A thoroughly detailed list of changes will be maintained on the
> ClusterLabs wiki:
>   https://wiki.clusterlabs.org/wiki/Pacemaker_2.0_Changes 
> These changes are not final, and we can restore functionality if there
> is a strong need for it. Most user-visible changes are complete (in the
> 2.0 branch on github); major changes are still expected, but primarily
> to the C API.
> Some highlights:
> * Only Corosync version 2 will be supported as the underlying cluster
> layer. Support for Heartbeat and Corosync 1 is removed. (Support for
> the new kronosnet layer will be added in a future version.)
> * The record-pending cluster property now defaults to true, which
> allows status tools such as crm_mon to show operations that are in
> progress.
> * So far, the code base has been reduced by about 17,000 lines of code.
