I’ve heard about the “save the battery/warranty” argument a lot now about why Ford is being conservative while Tesla isn’t.I hope that Ford does release some kind of improvement. I don't think anyone is expecting 100% power indefinitely, but something longer than 5 seconds, or with a more gradual taper rather than a cliff, sounds reasonable.
I work on stationary grid storage, and work with all the major battery vendors - they often have very strict, but somewhat silly, operational requirements, because from their perspective it is easy to be simple and strict than to follow nuance. One example is a vendor that requires their BMS to turn off if humidity goes above a certain level - we worked with them to do the opposite, if the humidity goes up, increase power to warm up the system and reduce the risk of condensation. In this case I can imagine that a gradual roll-off could be just as effective as a cliff, and far less noticeable to drivers.
Of course, one counter example to keep in mind is that some manufacturers may be willing to sacrifice their future warranties in order to sell more cars today... I have real concerns that part of Tesla's overvaluation is the massive warranty obligation they are sitting on.
However, Teslas have been on the road long enough for us to figure out if there are a ton of battery warranty claims. Is that the case or are we just making excuses on behalf of Ford?
