In the official BIPM brochure, hours are technically classified as "Non-SI units accepted for use with SI." This puts them in the same category as liters, hectares, tonnes, decibels, etc.
I can read Wikipedia too. All the calculations are done in m, s, g, etc. if you want to dumb it down to the public you might as well go in miles per hour, leagues per day, etc., spaceflight is not the place where it is appropriate.
> spaceflight is not the place where it is appropriate.
But, a video stream meant for the public consumption is. SI are standardized for the context of calculations, not necessarily for human consumption, which happens to be why nobody gives the weather in degrees kelvin.

1. Quick, call the spaceflight units police.
2. When you ask the regular units police (BIPM), their official decision is that hours are "accepted."
I trust you can read the dictionary definition of "accepted" all on your own.

I'm proud of you?
Presumably you can also read the official BIPM SI Brochure. As mentioned, it will tell you the same thing:

The blue origin launch this week used mph and feet of elevation, and I can definitively say that using modified SI is way way better than US customary
