Clutch sticking half way to floor

I'm not sure I entirely agree with this. I don't see how the MC can influence SC failure.

The reason for replacing the MC is because of difficulty in bleeding the system when replacing the CSC. This becomes an issue on higher mileage cars, not brand new cars. For lack of a better term, an "aged" MC has more wear inside and may leak (to some extent) internally. As a result, it's difficult and/or impossible to get air out of the system.

On a car with 1900 miles (OP), this should not be an issue. After the car is aged - 50, 60, 70K miles, and clutch/csc replacement is necessary, then absolutely, replace the MC too.

My recommendation, change the fluid in the reservoir once a year. Use some kind of suction device to suck out most (not all) of the fluid from the reservoir. Replenish. Drive the car a few days then repeat. Do this 2 or 3 times to renew the fluid. Every 2 years do a thorough flush. Doing this removes contaminants from the clutch line and should prolong life of the entire system.

Edit: I should add, failure of a CSC on a brand new car is very discerning. Doesn't inspire lots of confidence in the build quality. Usually they fail later, 40-60K miles.
