Agreed. I'm going to implement support for qgisMinVersion method
(you're right, it's clearer) to distinguish which plugins can be
loaded safely.

QGIS versioning scheme is "x.y.z" where x,y,z are numbers, sometimes
'z' can be omitted and is considered as zero. So I think there
shouldn't be a problem comparing the versions.

This sounds like there's need to add minimal version tag also to
repository's XML.

I prefer to be strict and require qgisMinVersion in every plugin.
However I don't know whether we really need qgisMaxVersion as max.
version can't be usually predicted and I suppose that developers will
ignore it or put some arbitrary high version numbers.
