Phonology is not irrelevant, but it is not paramount either. If you develop vocabulary you'll also develop phonology at the same time.

Phonology and vocabulary in Delang was developed side by side, each adjusting to each others needs. Then after some vocabulary existed the phonology was set in stone. However Delang is open for dialectal changes.
