I elaborated on it below. Your team will grow and shrink. No guarantee that each developer will bring the same IDE. This is especially true for open source projects.
If it works your team, no need to be dogmatic about it. Just be careful about what you put there and agree on a set of sane defaults with your team. Your project should build and run tasks without needing a specific IDE.
What a nostalgia trip. I love it. I owned and used 3310 for several years back in early 2000s.
How did you end up drawing all of these? Do they serve a purpose or was it just an artistic pursuit?OP has already provided details in the post description.
