But what is the sense to compare on a single feature? Obviously, Django doesn't cover 100% of use cases but, usually, you choose a technology that simplify you live overall not on specific aspects.
Django is the community we are historically very attached to because that's what sentry is written in. The numbers in what we give to open source do not correlate with our business interests or strategies. Python is not the largest sentry consumer base :)
That is also why Rust and rrweb are overrepresented.
