Valve Confirms Steam Frame is Still Coming This Year, Now Marked as "coming soon"

Anyone knows if the controllers will be rechargeable?

AA batteries are what it shows on the Steam Frame store page. Text is

Easy battery access​

Each Steam Frame controller runs on a single AA battery, offering ~40 hours of play time.

I know this, but if I use rechargeable AA batteries, will I be able to charge them without removing them from the controllers? Like through usb-c?
Third party manufacturers have a workaround for quest 3. They made their own batteries with their doors for their wireless charging dock.
Why is valve going into this highly impractical decision?
Having to replace batteries is impractical?

Much rather, replace the batteries myself than having the controllers go bad at a later date.

I despised the quest pro controllers… Always losing sync, turning on and not charging when you want to use them.
