Short version: Not while they sell.

: I think you've forgotten their Special Snowflake status. Codex Space Marines is the wrong codex to answer this question. There are a few new Primaris-only chapters noted (in the Dark Imperium novel as well), but not so much for the Blood Angels. Baal is only mentioned because Guilliman happens to grace it with his presence.
From what we DO know, the sons of Sanguinius were nearly wiped out by the Tyranids before Guilliman got there, including 4 Chapter Masters getting eaten (surprising absolutely no one, despite the carnage everyone with Special Character status will likely survive anyway). This means what survives of them will probably be rebuilt on a Primaris foundation.
It also means Gabriel Seth might get to play with a full Chapter now.
We'll likely learn more in Codex Not Space Vampires Dammit.
Ask not the Eldar a question, for they will give you three answers; all of which are true and horrifying to know.
