It requires republican house and senate members to go on formal record that they are willing to accept Trump’s abuse of power and declare “party before country”
If that was the case then the articles would have been sent over immediately after they were voted on. The problem is that the House majority thinks that they can run the Senate. To the contrary, the Senate has the sole power to conduct impeachment trials. If they don't do their jobs, the sole remedy is to vote out the current senators and replace them with new ones. The idea that Pelosi and the House have any say over the impeachment trial is pure non sense. The longer she holds on to the articles, the worse it's going to be on the Democrats.
Most people I know, even people that hate Trump, don't even give a shit anymore because it's dragging on so long. What Pelosi is doing is the equivalent of a coach who is down by 21 with 1:30 left in the game using all his timeouts like it's going to help win.
