It does if you want to use unity builds at some point down the road. For my app it took the build time from 25 minutes to 2 - 3 minutes which is critical when doing CI on a lot of operating systems and with a big build matrix.

I am not familiar with unity, but why should it slow down builds?

From a quick google, unity builds are akin to #include-ing every file in the project (yes, the .cpp files too).
