I can't speak to the Block Equivalency Files, but when I asked the Geography guys about the Block Allocation Files -- which seem to me to be the same thing -- they replied:
There are no plans to release BAFs for the 118th Congress or 2022 SLDs. The BAFs are only created for the decennial release.
EDIT: Looks like the BEFs are a product of the RDO, not the Geography division. I've sent an email to RDO asking about the BEFs.
As for Geocorr, it'll be updated this summer. I'm a one-person shop over here, and believe it or not, MCDC isn't my only gig.
