discussion: Import maps should be an unstable feature

[lucacasonato]

Deno is currently the only runtime that implements import maps. They are not supported by any browser at the moment.

• Chrome: did an origin trial from M74 to M76, ending September 4th 2019. No action since then. Currently not scheduled for an upcoming release.
• Firefox: position unclear (Import maps mozilla/standards-positions#146). Not implemented or experimented.
• Safari: No signals. Not implemented. No tracking issue.
• Node: No signals. Not implemented. No tracking issue.

We are taking quite the risk by implementing this spec and supporting it in stable before it becomes a w3c standard and is implemented by other runtimes. I think we should move the entire import map feature under the --unstable flag.

Yes I’m all for it. We should make it fail without also specifying —unstable flag. Can be implemented using State::check_unstable()

I'm on it.
