I am yes.
The ones linked earlier do not make this clear. I went to Set up a local Discourse Development Environment?, and selected Install Discourse on Ubuntu or Debian for Development as I am running Ubuntu 22.04.3. This page does say that you don’t have to run the entire script, but only in small text after the part that instructs users to run it.
To me this was not clear, since when reading the instructions top-to-bottom one would naturally assume they have to finish the current step before continuing. So I fought the installation script, only installing what I needed, only to then continue reading after finishing to see that that was intended the whole time and I didn’t have to actually fight with anything.
Putting that disclaimer after the instructions definitely doesn’t make them clear, imo.
