curvedsky.alm2map (and possibly other related functions) have lost some flexibility in handling the shapes of inputs. For example, if alm is (nelem,) shaped and the output enmap has shape (1,Ny,Nx), then it returns the following error:

What I Did
The following code will work in v0.17.0 but not in v0.21.0 after the ducc0 transition.
from pixell import enmap,curvedsky as cs,utils as u
import numpy as np
import healpy as hp
shape,wcs = enmap.fullsky_geometry(res=16.0*u.arcmin,proj='car')
lmax = 500
alm = np.ones(hp.Alm.getsize(lmax))
shape = (1,)+shape
print(alm.shape)
print(shape)
cs.alm2map(alm,enmap.empty(shape,wcs))
