Adding to the praise of "it just works". My Dreame L10S Ultra was straightforward to root after getting the breakout PCBs required. Now it only talks to NTP and the update server when I remember to check for updates every few months.
I don't have any links for assembled boards, but there seem to be some available [1]. You can find the PCB files here [2] including more documentation. The same page also has a Telegram group link to find people near you who might be able to help out.
I got my PCBs made via JLCPCB, but there are other options as well. Pay attention to select the correct PCB thickness, noted in the Readme. I fell into that trap and had to order again. Sourcing the USB port with the correct footprint was a bit annoying, I just ended up ordering a selection of kits with multiple variants from Aliexpress.
