CMV: if you support court-packing and it isn't about increasing power, you should advocate for increasing judges slowly over time

So I'm not from the US, but I have a reasonable understanding of how the system works. Biden now wants to add 4 judges to the supreme Court at once, which would swing the court in the Democrat's favor significantly.

I've heard some reasonable arguments for increasing the number of judges, and I'm willing to go along with some of them. However, it not only opens the door to abuse (the next Republican president can just do the same thing) but it's also pretty transparent that this is being done at least partially for the purpose of gaining power.

If that isn't the reason you support increasing the number of judges by 4, you should be happy to accept a slow increase in judges over time, or even-sided nominations.

I would see three choices:

1. Biden is required to nominate 2 Republicans and 2 Democrats. If you think the need to increase the court size is urgent, this seems to satisfy that while also not effecting the balance of power.

2. Biden nominates 1 judge, the next republican president nominates 1, then Democrats, then republicans again. This seems *more* fair as republicans would get their choice, rather than having one of their number picked. But I recognise that this could take 20+ years, so isn't particularly quick.

3. Each presidential term can make one nomination, starting with Biden's current term. This has the potential to still have all 4 judges be democrat, if Biden wins re-election and his successor serves two terms as well. But, you can argue that this would at least best represent the will of the people, and could potentially see republicans nominate 3, if they win all 3 of the next elections. Again, not as urgent as 1, but at least will be done in 12 years approx. 

Personally, I'd suggest route 3. But my opinion is that if you're not willing to accept any of the above 3 options, you are clearly only supporting increasing the size of the court in order to swing the balance of power in your favor.

EDIT: Apologies, shouldn't have specified adding judges over time in the title, as I think option 1 is also reasonable. What I mean is:

If you support court packing and it isn't about power, you should support one of these three options.

Two of the last three SCOTUS nominees were chosen by the GOP with questionable methods including a 180 degree flop of logic as to choosing a SCOTUS in the final moments of a POTUS term, The third candidate was an embarrassing circus that many Americans were ashamed to see. 

Biden's reasons to enlarge the SCOTUS are about undoing the harm the last guy caused. This can only be corrected now. All of OP choices avoid the need to correct the injustice in the Justices court.
