I suppose it depends how hard it tries to relock the bootloader; if I can tell it once to not do that then perhaps it's fine, but I don't want to risk a misclick soft bricking the device.

Although as an extension of that - I'm hesitant to use software written by people with such a philosophical difference. It might work today, but I wouldn't trust it to work tomorrow.

Same thing can be said for LineageOS too.
