Clobber & Overwrite?

Astropy 1.3 spews deprecation warnings when using clobber now. I’m happy to shift from clobber->overwrite but I have codes that need to maintain compatibility with astropy 1.0+, and I don’t want these to throw deprecation warnings everywhere. Is it possible to backport the overwrite change so that all versions of astropy 1.* support both (with deprecation warnings)? (this is really a policy question regarding minor version changes; I’m sure it’s technically possible)

So what about just removing the deprecation warning in 1.3.1 and re-introducing it in 2.0 LTS?

Just FWIW, if other people are struggling with wrappers etc., I dealt with the change like this (in __init__.py), which also works with the writeto method:

if 'clobber' in inspect.getargspec(astropy.io.fits.writeto).args:
    arg_overwrite = 'clobber'
else:
    arg_overwrite = 'overwrite'

and

from . import arg_overwrite

hdulist.writeto(filename, **{arg_overwrite : overwrite})

While I certainly wouldn’t want to get stuck with a bad API in the name of backwards compatibility, we (Gemini) also find this kind of change a bit disruptive for only cosmetic reasons (more or less)… 😉.
