If the 4680 cells handle the charging as expected, increasing the max output of the SuCs should result in a faster charge for the 4680s (and beyond). The "tabless" design of the 4680 is the part of the secret sauce that will make that battery geometry popular and will likely encourage the increased adoption of EVs (and the reduction of the time it takes to SuperCharge).
There are a bunch of changes coming down the pike. 4680 cells should help with charge speed a bit but Tesla Silicon is the big one for charging speed and it’s not clear that’s coming on the 1st gen 4680 cells.

From the conference call:

”Andrew Baglino” said:
Yes, yes. Sure. So throughout 2021, we focused on growing cell supply alongside our in-house 4680 effort to provide us flexibility and insurance as we attempt to grow as fast as possible. As we sit today, sales from suppliers is actually -- it sort of exceeds our other factory-limiting constraints that you mentioned, Elon, in 2022 or to say differently, 4680 cells are not a constraint to our 2022 volume plans, based on the information we have. But we are making meaningful progress of the ramp curve in Kato. We're building 4680 structural packs every day, which are being assembled into vehicles in Texas. I was driving one yesterday and the day before. And we believe our first 4680 vehicles will be delivered this quarter.

Our focus on the cell, the pack and the vehicles here is driving yield quality and cost to ensure we're ready for larger volumes this year as we ramp and next year. And the 4680 and pack tool installations here at Giga Austin are progressing well with some areas producing first parts. And the internet has also noticed that. Yes, I was touring the factory -- the cell factory here. I’m super pumped. It’s like a really exciting accomplishment for us to bring everything into one Austin factory here in Texas.
Highlighting mine. Sounds like for Model Y production at least they expect to have no trouble producing enough 4680s for volume production. By year end, that will mean 5000+ Model Ys per day with 4680 cells rolling out of Texas. No 4680 cell production in Texas yet. But they are already producing parts out of some areas. Texas 4680 cell production is what we are most interested in for the Cybertruck.

Cars coming out in the future with newer batteries might not have that limitations, and this is prepping for that. (In theory). (Think 4680 cells)

In regards to home charging, you would never want to exceed about 80% of the maximum breaker rating.
It's not a question of want to, it is one of must not. Code requires derating of EVSE circuits to 80%. The current crop of chargers across OEMs seems to be rated at 48A (11.52 kW - input) max. EVSE that will deliver that maximum must be on a 60A (or greater capacity) circuit.

So uhh, there are reasons you don't want to other than 'law says so'.

Duh.
