I have seen/heard of audience members getting to go backstage (and/or stand onstage) at Broadway shows but I think that in almost all of those cases they have had a personal connection (like a family friend or relative) to someone in the cast or someone working on the show. For most people to have interactions with the cast, the stagedoor is the place to do it.
Yes, stagedooring and backstage guests aren’t a thing currently due to the pandemic, and my guess is it’ll be a while after Broadway reopens before they return (at least until masks aren’t required anymore I would think) but for people saying that Covid has put an end to those things forever, I highly doubt that’s true. Once enough people have been vaccinated and the virus is behind us I fully expect those things to come back. Of course though, it’s up to the individual performers if they choose to come out to the stagedoor/invite backstage guests, and if they choose not to for whatever reason, their decision should be respected.
