There were two interviews that referenced it actually:
From the Icy Veins summary, they reported:

They talked about PvP relative Item Level for PvP Gear (similar to what we had back in WoD). The idea they are discussing is shifting back from how PvP gear worked back then, when there were 2 item levels, so gear went up to Item Level 232 in PvP, making it the best to wear in PvP scenarios.
From the Vanion summary they reported the following. We’ve pasted the original text in German and the Google Translated version below:
Vanion said:
Die Entwickler überlegen aktuell, ob man bei der PvP-Ausrüstung wieder zurück zum System von Warlords of Draenor gehen sollte. Dass sich PvP-Ausrüstung dynamisch anpasst und ein höheres Itemlevel bei PvP-Aktivitäten bekommt, wodurch es immer besser ist PvP-Items zu nutzen statt PvE-Items.
The developers are currently considering whether to go back to the Warlords of Draenor system for PvP equipment. That PvP equipment adapts dynamically and gets a higher item level in PvP activities, which means that it is always better to use PvP items instead of PvE items.
