Still an election year and a few weeks difference isn't going to keep the Democrats from screaming 'hypocrisy'. And I can't say I'd blame them; McConnell chose to give the Biden rule as his excuse. He'd have to live with it.
The choices were pretty clear in 2016, but 2020 will have a lot of radical "amateurs" running, like O'Rourke, Harris, et. al. Republicans should counter by saying that the field is still too open to say that the voters should decide.
Once the field narrows to the top two, then that's different.

You may be right.
However, the Dems in the same situation would push on and we will, too.
We have the Senate and we push it.
