This is a good question. Here's my theory:
Having given drifting a "spin" myself, recently, and watched a few people on drifting servers do their thing, I suspect that drifting in its CURRENT form will be a thing of the past.
This will possibly annoy a few people, who are managing to catch AND HOLD drifts when in REAL life, they wouldn't. The new patch is primarily about bringing more realism to the tyre physics. From what I've observed, a lot of "drifters" at present are exploiting a physics bug that is going to be reduced significantly, according to the main website's update from yesterday.
The new patch will be GOOD for those drifters who are using LFS to simulate real-life drifting. They will welcome it, even though it becomes harder, BECAUSE it becomes more real.
Also, drifters who can STILL drift after the patch will carry more credibility within the rest of the community, I think, because everyone knows right now that a) drifting on LFS has been an exploit, and b) real-life drifting is a challenging skill that must be learned intensively in order to successfully achieve.
