[mpl_toolkits.axes_grid1] Can't remove host axes' twin axes #4896

Axes created via mpl_toolkits.axes_grid1.host_subplot(...).twin() (or twinx(), twiny()) can not be removed via their remove() method. Non-mpl_toolkit twin axes can be removed; this is specific to mpl_toolkit.

Example:

from mpl_toolkits.axes_grid1 import host_subplot
h = host_subplot(111)
t = h.twin()
t.remove()

raises NotImplementedError: cannot remove artist.

Is there a way around this that I'm missing? I'm using axes_grid1's twin() to interactively create axes with user-defined transforms and want to be able to destroy them as well, of course. Alternatively, it would suffice for me to be able to change the transform (given initially via twin(aux_transform)), but even that seems not possible.
