From MNIInfant docs:

NOTE that these templates are smaller then standard MNI-152 template, so if you use them to perform registration in stereotaxic space it will be different coordinate system. It is possible to transform results to MNI-152 space by applying following scaling: 1.21988 in x direction, 1.23510 in y direction and 1.28654 in z direction. Also, you can apply transformation defined in nihpd_asym_44–60_tal.xfm file.

Is there an ETA for this enhancement?

This is needed for compatibility with XCP, and therefore, CABINET (HBCD MRI processing).

Thanks!

IIRC I think the plan is to use space-MNI152 in the output filenames (checking in with Ted and Azeez), and the conversion should just be:

def scale_to_MNI152(img):
    affine = np.diag((1.21988, 1.23510, 1.28654, 1)) @ img.affine
    return img.__class__(img.dataobj, affine, img.header)
