I think I used the wrong word there - by capacity, I meant more of how much I am able to deal with at the moment!

If I introduce a new app identifier for the nightly builds, I have to then effectively manage two separate app releases/streams, which will take up time that I could use to work on new features or fix existing issues with Thunder. It's currently a lot simpler for me to just change the version build to identify pre-releases vs. the more stable builds since that's a one-line change for me to do

Hopefully that makes sense!
