Perhaps there have been changes since then.

I created a 48 pin UFQFPN PCB for L5xx with pads extended a bit outside the package, then hand soldered the flanks with a 1/8" chisel tip and liquid flux. That worked well as a prototype. For qual testing and  production robots, solder paste and reflow ovens are probably the method of choice.

Perhaps, but there's been no follow up. Used 20, 28, and 32 pin UFQFPN here for their compact size, and production's dislike of WLCSP

Would have liked to see 20-pin UFQFPN for the C0 and G0's, but suspect the die's too big.
