I didn't get the impression that anyone cares about the source or destination language. I think the concern is centered around the long history of failure with large scale rewrites like this-- See Netscape 5, Perl 5, etc. Joel Spolsky wrote a legendary article about this [0]. I think the NextJS app router might be slowly joining this conversation as well.

It could get even worse if they get Second System Syndrome[1] and try to add features as they rewrite it. Considering Bun's rapid development cycle, this seems likely.
