Actually this is already implemented. In QGIS 3.0 there is also GUI to
configure the min/max zoom level for XYZ tiles. In QGIS 2.18 it is not
available in GUI, but it can be still configured when adding XYZ tiles
layer in Python - one just needs to specify "zmin" and/or "zmax"
parameters in data source URI.

In general it is better not to assign developers to bugs unless they
told you so in a prior discussion. It can also confuse others to think
that a bug/feature is being actively worked on while it is not. If you
want to make someone aware of a particular bug, you could add them to
the list of watchers of a ticket, so they get notified...
