Both items concern the btree module not being available on certain ports. The query (issue #6186) asks why Pyboard D (stm32) lacks btree. The candidate PR #7106 re-enables btree for ESP32 (fixing a separate regression tracked in #7101). The PR does not touch stm32/Pyboard D at all — it modifies esp32, rp2, and zephyr CMakeLists. The query's underlying concern (stm32 btree omission) remains unaddressed.
Suggested action
Leave issue #6186 open. The stm32/Pyboard D btree question is still unanswered. PR #7106 can be referenced as context showing btree was re-enabled on ESP32, but a separate stm32 change is needed to resolve #6186.
