You will get the new astropy version in 2018; I just wait for a fix on a build dependency (sphinx-astropy) to be installed on the buildds. That is probably quicker than autoremove.
@sandro: Triggering of auto-removal is not part of the list of reasons for severity "serious", as you already pointed out yourself some time ago: https://release.debian.org/buster/rc_policy.txt Delayed migration is *not* in the list, so raising severity for the goal of package removal in testing (to let other packages migrate) is abusing the severity system.
