The only problem left with the upgrade is that this no longer works:

import geoviews as gv
import geoviews.feature as gf
import xarray as xr
from cartopy import crs

gv.extension('bokeh')
gf.land.opts(projection=crs.Geostationary())

Where these work gf.land.opts(projection=crs.Geostationary(), scale="10m") and gf.land. Another problem is that opts are saved on the FeaturePlot even if you instantiate it.

The last two commit (9eb60be and f12a1b3) fixes the last of the problems I mentioned in the previous post.

import geoviews as gv
import geoviews.feature as gf
from cartopy import crs

gv.extension('bokeh')
(gf.land().opts(projection=crs.Geostationary()) + gf.land()).opts(shared_axes=False)

Thanks @hoxbro! Pretty happy the changes look pretty minimal and all look good to me.
