If there's feedback that's relevant to an open PR, the correct place for that is in the comments of that PR. It's not appropriate to make new PRs that completely contain existing open PRs.

One big reason is that involving the original author of a given PR can help avoid obvious errors, like:

• adding a second loop to check modules/csg/icons but not noticing that 5 other modules also have icons
• changing the behavior of the final "writing icons" section to no longer overwrite existing icon files, when the point is to make sure this extension's icons match the latest versions from the editor
• adding unrelated configuration changes that, as previously mentioned, belong in their own PR
• pointless changes like forEach -> for loops that have no impact to you since you aren't going be maintaining this code in the long run

It's unfortunate that this PR was submitted this way, because there were a number of real mistakes in my original code and you fixed several of them. If this feedback had been in the correct place, I'm sure we could have had a productive discussion, I could have learned a lesson about proofreading, and both of us could have avoiding wasting our time with this whole episode.
