Ladies and Gentlemen, I have just finished reading "Descent into Avernus". Below I present the only two passages alluding to CHARNAME:
"Over the years, Baldur's Gate has harbored countless evil schemes and conspiracies. Perhaps the most dastardly, though, was that perpetrated by Bhaal, god of murder. who foresaw his own death during the Time of Troubles. While in mortal form, Bhaal conceived multitudes of offspring, plotting to have them resurrect him. They actively hunted and slew each other, with the survi·vors collecting ever more of Bhaal's godly essence. Sarevok, a Bhaalspawn and member of the Iron Throne merchants' guild, sought to spark war with the nation of Arnn and become the new Lord of Murder. Another Bhaalspawn, aided by powerful allies, thwarted Sarevok's plan and brought stability, if not peace, to Baldur's Gate once more. Yet, Bhaal and his faithful have menaced the city ever since."
And later on:
"Every now and then, rumors surface that a powerful political figure is a Bhaalspawn."
It seems that something is brewing with Larian/Wizards of the Coast, and whether on not Abdel Adrian will remain a canonical CHARNAME is still up in the air.
