Ok I found this (regarding my question)
“Discourse is designed for the next 10 years of the Internet, so the minimum browser requirements are high.”
I’m not sure I understand the message, unless Discourse is developing inside a time machine. I would expect the majority of users in 2030 are not using the product today. Maybe I’m missing the point.
EDIT:
@Canapin what is the browser support policy? Current stable - 2 (N-2), or N-1, or only “latest”?
Security concerns highlighted here (more concern on the user’s behalf rather than specific to Discourse use I’m sure), there really can’t be something Discourse requires that isn’t supported in core JS libraries that haven’t changed much in 6 years. Even Gmail via the web browser on these older devices work well, without issues. Security concerns aside, already noted here.
