Line 20 in 6f7da41

export const DENO_VERSION_RANGE = '1.39.0 - 2.2.4'

we still do allow deno 1 in allowed versions. The comment say we should include it? Or change the range in deno/bridge?

Without changing the value in CI, I get all the test failures in the first commit and requires quite a few code changes in addition to the default flag value change. Changing the flag default is effectively changing the accepted range in deno/bridge but without removing the feature flag (since we would like to keep it around until the release is in the clear). The next release of build after this one will be removing the feature flag and cleaning up all the remaining code, but to keep the change set small in case a revert is needed, this was the path selected. Open to alternatives.
