I agree completely, it's a very strange objection - Rust is one of the very best languages for web servers. I wish I could use it at work instead of Django.

I think some C/C++ devs take a perverse pride in their language not being suitable to write web servers, because webdev is not real programming anyway (excepting the 'systemsy' parts like nginx).

Well, Rust is great at systems, great at web servers, pretty good at one-off script, even pretty usable for frontend. Every time I hear someone pigeonhole it as just a systems language, I think - you're missing out.
