Recent changes to the snapshot have radically and unpredictably changed the behavior of ALL minecarts. This means that any machine based on the old physics needs to be torn down and rebuilt, and many machines relying on compactness and combining hoppers with rails now may have no effective way of combining powered and unpowered rails to achieve the pace required to, for example, evenly distribute items across multiple hoppers. This is ridiculous. A new rail to induce the new physics would have been acceptable, but to break any machine based on the old physics without any real community input is just dumb.

You haven't listed any specific issues, thus this ticket is invalid. There are a bunch of (very specific) bugs already on this site regarding the new minecart physics, please review those before posting any new one. Also, keep in mind this is a recent and major change, it will almost certainly be tweaked in the next however many snapshots before 1.8. If you wish to make general complaints, feel free to use Reddit, Twitter, or your favourite social platform.
I think the physics are great, when my cart was full of items it became a lot slower and broke my system, but all I had to do was add more powered rails and it still worked fine. It requires a lot of extra gold, but it was worth it. It is something I would want to stay. It seems more importance is being placed on gold with no village breeding without trades, gold is an easy way to transform villages from zombie villages. Also, from what I have seen and witnessed in my world, carts would still travel at least a certain distance. But again, to each their own, I like it.
I believe this is my community input haha.
Further info: the impacts to existing long distance rails links are extreme, as well. How are server admins expected to fix hundreds or thousands of blocks of rail links on their servers? This change is akin to changing the max signal from redstone torches from 15 to 31: it changes everything and breaks almost anything that works today. It's a change to an underpinning principle that it doesn't seem there was much community call for, and a change that could have been handled with a new block, an 'accelerator rail', for example.
