It all depends if the industry will act this way or not, I still hope that there is some level of desency left somewhere, because being too paranoid about all of it will not get me anyway either. Also the utility of all this analytics data is limited, for example they could possible get the 'number of lines of code' written by someone, but it is impossible to judge how essential all these lines of code were to the business. Also there would be a significant backlash, if they get too invasive on the privacy of developers. (that's the moment for the video where Steve Balmer is flipping out on stage and shouting 'developers' https://www.youtube.com/watch?v=I14b-C67EXY )
Some manager may toy with an idea of getting IT to install and manage monitoring software, but ultimately reject it as not worth the cost. But if the company starts to work over something like Codespaces - even if only for purely technical reasons - then suddenly they'll find themselves having a dashboard for free, and for sure they'll start using it.

now there is a bit of an irony - github helped open source, now this development will be very helpful to corporate software developers, but might turn out to be harmful to open source as such.
Therefore the real question is if Codespaces is helping to get your job done; I guess that depends on the complexity and structure of the code, the complexity of the build environment/how you work with the CI environment and how the project is being deployed. I guess that this complex of issues will increasingly dictate how things will get done - if these are too complex, then you are better off with a remote environment.
