What's the motivation for the new strings? Are they formatted after anything standard?

The thing is geth itself doesn't use BalanceChangeReason type for anything meaningful (as of 1.14.0) i.e in any of the tracing code, but gives us the freedom to decide how and where we use it.

They aren't formatted after anything standard but gives the reason for the balance change itself, which I thought we could use in tracing, let me know if I got it wrong.

For example geth's current master uses BalanceChangeReason this way https://github.com/ethereum/go-ethereum/blob/6d3d252a5ece0687dcaaf197e0bfc03466161ff1/eth/tracers/live/supply.go#L191-L208

earlier in the purpose field of beforeEVMTransfers and afterEVMTransfers we had single word strings like feeCollection, tip etc.. but now we could have a more descriptive reasons with the String() impl like in the above comment

...

I am not sure, but I guess someone is already parsing the exiting short srings.
If they are - this change would hurt them, and I rather avoid it.
We could still have a "String" function but have it return the old string to avoid compatibility errors.
