@panteliselef Following-up here, per our DM:

This all looks cool, but I'd suggest that we use specific flags vs __DEV__ directly.

It'll make it easier to follow over time, and if/when we need to remove it.

Seeing as we only need it in the dev environment, the flag could follow a format such as __BUILD_FLAG_ACCOUNTLESS__, and rely on the same conditions as __DEV__.
