Hi there,

Just realized that I replied directly to Sohom instead of using "reply all"
on Monday. Sorry about that!

To ensure that folks are aware, I added a new FAQ page
<https://www.mediawiki.org/wiki/MediaWiki_Product_Insights/Artifacts/API_Strategy_Brief/FAQ>
to the API Strategy Brief
<https://www.mediawiki.org/wiki/MediaWiki_Product_Insights/Artifacts/API_Strategy_Brief>
to
respond to many of these and other questions related to the brief.

Please take a look, and keep the questions coming! I would love to keep the
conversation going.

Cheers,
Halley
