I haven't seen this posted yet, so I'll do it even if it makes me look stupid.
If you, by some miracle, land a 6C on someone in the corner and try to start a DP loop, delay 623B for like, 3 frames.
The opponent will be slightly higher, compared to an instant cancel.
From there, landing another 623C is cake.
And, is it just me, or is Jin's 6C dash cancel window slightly smaller now?
