I am afraid we can't add Kubo-specific hacks like this to implementation-agnostic test cases.

Let's park this until we have #185 (comment) sorted out.

FYI I just tested this against https://github.com/ipfs/helia-verified-fetch/pull/85/files#diff-175730b97b315afceee1b708f9bd876588ef883662dc52e139a7961ac7804c56R100 and it doesn't seem to fix the problem

I am afraid we can't add Kubo-specific hacks like this to implementation-agnostic test cases.

I'm confused.. This PR is attempting to allow an escape hatch for dependence on Kubo specific behavior.

[lidel]

Sorry, what I meant is that we should fix conformance tests and not introduce configuration with "kubo" in name to work around have dependency on Kubo specific behavior.

I'll see if we can do this in generic way, without any workarounds.

Update: i'm tracking fixes in #185 (comment)

[lidel]

Hardcoded matrix that run subdomain tests against localhost is removed in #211, which will ship in v6, so closing this one.

Once that PR is merged, tests will be run against --subdomain-url, and there will be no implicit tests against host that was not explicitly passed via this parameter.
