The one context where I've seen something like this that I thought was interesting was in an online MOOC. Presumably it would be trivial to give your account credentials to someone else in order to have them pass a quiz/test on the platform for you, or to write our essay. They used something similar to match the typing pattern compared to some other sample that had been taken when identity was verified off-band, so then in subsequent submissions of writing samples in the platform, they could have more confidence that it was submitted by the original student.
In 14 September 2019, Europe adopted the PSD2 payment standard which require banks and fintech's to integrate two factor authentication solutions. The typing biometrics can be integrated with other 2FA methods, increasing it's use and importance.
PSD2 is the second revision of the Payment Service Directive (PSD, 2007), which is aimed at developing the market for electronic payments in the EU. The different measures highlight the opening for other companies to use banks payment services (Open Banking) and two-factor authentication (2FA) to increase security in transactions and prevent online fraud.
