Bug summary

I have not been able to find a supported method for removing axis sharing that has already been established. At least, not without removing and re-creating the axis.

In older versions of matplotlib, it was possible to do:
ax1.get_shared_x_axes().remove(ax2)
but with the new axis grouper API, this is no longer possible ('GrouperView' object has no attribute 'remove').

There does seem to be a workaround using an internal variable:
ax1._shared_axes['x'].remove(ax2)

I would suggest that a natural way to support removing all axis sharing might be a method:

ax.set_shared_xaxis(None)

or possibly

ax.sharex(None)

Code for reproduction

import matplotlib.pyplot as plt

fig, (ax1, ax2) = plt.subplots(2, 1, sharex=True)
ax1.plot([0, 1, 2], [1, 2, 3])
ax2.plot([0, 1, 2], [3, 2, 1])

ax1.set_shared_xaxis(None)

plt.show()

Actual outcome

AttributeError: 'Axes' object has no attribute 'set_shared_xaxis'.

Expected outcome

Axis sharing should not be enabled.
