I think it's important to remember that the internet and online life is significantly more mature than it was when SGs were introduced - Facebook, Social Media and especially Discord have been game changers for building communities.
The SG as originally conceived was designed for friends to play together but since then other ways to play have superceded the SG in many ways. But, as MP3s came along, vinyl and cassettes didn't just go obsolete, and still have their fans and purposes. People can still form SGs and do all the things SGs do - including have shiny costumes looking alike if wanted. But we should remember that life moves on and we have to adapt.
Perhaps the better question is what do you want to make your SG? Nothing is stopping you for running one old school or you simply can own it as a storage dump. No wrong answers.
