Okay.

The fusion transactions thing is a trivial change that counts inputs and outputs on a transaction and omits the fee check (up to a limited amount of blockspace) if the ratio is <1/3. That's something that would take a programmer of modest skill who didn't even necessarily understand the code base not very long to implement. I don't have a strong opinion on the merits of it, I could see arguments for it being a good or a bad idea.

I can't comment on the wallet changes in general because it is closed source. Although I can say that displaying and importing tracking keys is also trivial (just displaying or reading some hex-formated numbers that exist in a wallet), and I say that in part because another cryptonote coin added that in open source several months ago.

Overall there is nothing here that would suggest anything other than "keep the appearance of development going so some fools will buy and we can eventually unload a good chunk of the premine".
