Where did you hear this? I’d be very pleased if that’s the case but have seen no indication of it.
I also dislike this one, this term really doesn’t make any sense to me as a catch-all for money transfers, that’s just not what it means, your Finances are your accounts overall, not transfers to Savings or something. Personally I’d keep Cash and add then add Savings, Taxes, and similar if that’s what you want in order to classify transfers out. Another huge missing one is housing or rent and mortgage - this is most people’s largest expenditure by far, currently without a category so it comes under the grab-bag of unrelated spending ‘Bills’.
I have a family, and spend lots of money on it. I don’t really spend much on Monzo (personal account), because family spending goes on the joint account. I’d also definitely want to combine this with other categories, because it might be gifts, eating out, shopping, food or education (if we had those categories 
).
This one I won’t use much, but can see how others would use it, seems fair to me. Maybe I’ll use it for some other type of transaction since categories are so limited.
There are quite a few other ones chosen by users over here which would be useful, perhaps Monzo should run a poll of users to find out what categories they want to use, because the new ones added don’t seem to address what people are asking for here on the forum at least:
The biggest one for me (and it seems for others) is Savings, I’d like to see Monzo start looking at classifying transfers to other accounts properly, Finances feels like a step in the wrong direction, and I’m worried that Monzo is attempting to use really broad categories for disparate spending which just doesn’t belong together in a misguided attempt to keep the category count low - we’re going to need lots of categories and to manage that in the app properly (auto-hiding unused, perhaps give us the option to curate which ones we choose from while still choosing from a monzo selected set), if monzo just accept that and start adding them, it would make almost all these problems go away.
