Meh.
It's old hat for the minority party to propose stuff their constituents actually want when there's no chance of it actually happening. That way they can look like they're doing something, without actually doing something. Vote tallies are also extremely calculated; people like Joe Lieberman (retired now thank FSM) and Sue Collins have made long careers of being "moderates" without ever taking a courageous stand on anything (except when the party secretly wants something to die and they stand to politically benefit from "defecting").
It cuts both ways. Whatever you think of "Obamacare", the grassroots Republicans want it repealed, so the GOP passed repeals something like sixty times while Obama was in office, which of course got vetoed every time. Now that they actually own all three branches of government, interesting how they just can't seem to get the votes to make it happen. I also remember back in the "Dumbya" Bush years, he had all three branches of government and a commanding majority in both legislatures. If ever there was a time to pass a bill killing Roe vs. Wade (if you wanted it dead, anyway) it was then, when his approval was at 90% and the whole country was distracted by war. That was fifteen years ago.
So, wake me up when this proposal grows legs.
