This certainly works well if you only need to track one account, but my finances aren't even _that_ complicated and I still have accounts I try to keep up to date with five different banks (hometown bank with checking/savings, two credit cards, employer-sponsored retirement account with Fidelity, and a three-fund portfolio with Vanguard). All of those accounts have 2FA, so logging into each one, navigating to the download screen, and downloading it into the right spot easily adds up to fifteen minutes of work.

Ironically, I've found that since I started to rely more on downloading the CSVs and importing them (as opposed to entering everything by hand), I've been entering things less regularly because of the increased start up time. If each account just had an API to pull transactions, I could schedule a job to download everything daily and life would be so much better.
