You are right. There are some things that I've gone through on IRI through members' blog posts, news items, etc. regarding EDFC as follows:-
.
1) IR is trying to work on straightening of platforms at stations like Mirzapur along with the tracks (both loop and escape lines) to remove PSR. Track renewal work at GMO was also heard about to finish PSR of 30 Kmph & upgrade trains' MPS to 130 Kmph (For AC) and 110 Kmph (For Non-AC).
....

2) IR wants to make the entire Howrah - Gaya - Mirzapur - Kanpur - Delhi Route 100% free of manned/unmanned level crossing gates and work seems to have been started in the 1st phase between Mughalsarai and Ghaziabad through ROB/FOB constructions to remove TSR. FOB construction work at GMO is also pending to finish PSR of 30 Kmph & upgrade trains' MPS to 130 Kmph (For AC) and 110 Kmph (For Non-AC).
.
3) IR plans to replace Manual Signalling with Automatic Block Signalling System (ABSS) between Allahabad and Kanpur for better train movement.
.
4) All the above points are meant to synchronize present HWH-GAYA-MZP-NDLS Old Tracks with parallel EDFC Modern tracks between Dankuni Jn and Khurja Jn. Abhishek Jaiswal Sir on IRI told me that signalling work on ALD-CNB stretch is left while its tracks won't be shared with platforms of stations like Hathras Jn, Tundla Jn, Aligarh Jn, Khurja Jn, etc. en route. So freight and passenger trains may use EDFC tracks if they have a Non-Stop MGS-ALD or ALD-CNB Run :)
