If they have different checksums then they are not same.

Your patch lack part which would write simplified checksums.ini file. 

I think that mirrors informations would be still handy as there were 
ideas to write wget-like tool for fetching sources which would use own 
database for informations about source locations. We could make use of 
format like this:

[DirectFB-1.1.0.tar.gz]
url0=http://www.directfb.org/download/DirectFB/DirectFB-1.1.0.tar.gz
url1=http://www.directfb.org/downloads/Old/DirectFB-1.1.0.tar.gz
md5=da30fa2748c7501913c8832a83e654ab
sha256=0ee87256a278079955d78e4f235c15a174afbb507b5434f1966cd3e5f5a3f23a
 
And any change to checksums.ini format would require updating 
contrib/source-checker/ scripts as they are used to check source mirrors 
integrity and to sort checksums.ini file.
