TCP connect API and port 443
I am considering using Workers as a scalable proxy for https://webvm.io, to replace or augment our current Tailscale backend.
As I was experimenting with this idea I quickly hit a critical limitation of unclear purpose: connection is not allowed to port 80 and 443. Port 25 as well, but that is not a problem and completely acceptable.
Now, the recommended solution is to "simply" use fetch, but this cannot work in our scenario, especially in the case of 443 / HTTPS.
The virtualized applications inside WebVM will send a TLS encoded stream over port 443, and it is not possible (without implementing a full MITM) to convert this stream into a fetch request.
I'd like to better understand why port 80 and 443 are disallowed and if there are plans to lift this serious limitation.
