Analysis

• Filed by a maintainer (James Opstad) as an internal tech-debt/tracking task, not a user-reported bug. It carries the internal label.
• The task is a cleanup: Miniflare currently strips redundant nodejs_compat flags to avoid a workerd error. The workaround can be removed once workerd stops erroring — i.e. it is explicitly blocked on an upstream workerd change.
• Created today with no activity concerns; not spam, not stale, not a duplicate, and not user error.
• Component maps to packages/miniflare per the flag-stripping description, though the actual removal is gated on the corresponding workerd behavior change landing upstream.

Recommendation

Status: KEEP OPEN

Reasoning: This is a legitimate internal tracking item created by a maintainer to record a follow-up cleanup. It is deliberately blocked on an upstream workerd change and should remain open until that change lands.

Action: Keep open as a tracking item. No reporter follow-up is needed. Revisit once workerd no longer errors on the redundant flags, then remove the stripping logic in packages/miniflare.

• Reproduction: ❌ Could not reproduce. Main branch lacks the flag stripping mentioned in the issue; the stripping only exists in unmerged PR Strip redundant nodejs_compat flags #15148 branch. Current workerd 1.20260811.1 still errors with redundant nodejs_compat flags on date 2026-08-04, meaning the upstream fix the issue awaits is not yet available.
