Bug#933034: Should we stop reassigning py2removals?

[Rebecca N. Palmer]

The Python 2 removal checklist currently says that on uploading a 
package as Python 3 only, one should reassign the removal bug to 
ftp.debian.org for removal of the old binary, not close it:
https://wiki.debian.org/Python/2Removal
Scott Kitterman wrote (in #938661):
The python-theano binary was automatically decrufted.  No rm bug needed.

As this bug looks like the reason for needing a manual step, and has 
been fixed since the checklist was written, should we remove that step?
