Have you noticed how terribly siloed Google is? How you cannot use Drive to sync Photos, how long it took to get "One Google" subscription that still doesn't cover all that many of the products, how after moving it takes forever to have all the various products to agree on which country you live in? Dang, a few years back every product was separately asking for my age. That's not only because integrations are hard, but most importantly getting access to another team's data is a whole ton of lawyering through the privacy working group.

Now, that is for data that has no special legal protections. Whereas medical data is, for good reasons, subject to pretty heavy handed laws. Differing quite dramatically across all the diverse jurisdictions Google runs in. Sure, I have no clue what my employer's grand plan is here, but it will surprise me very strongly if medical data starts finding its way to established products. And note this is "medical data" according to the conservative common denominator across all the jurisdictions Google has to care about.
