As Takeyama-san mentioned, the version number downgrades would cause a problem ("zypper up" won't work while "zypper dup" would be OK).
There can be some trick to overcome, but better to ask on opensuse-packaging ML.

Too bad that we started with the high tentative version number...

Reopening, as @jengelh wrote.

Thank you for your submission. However, at least, version numbering style change must be noted in the change log.
