Yeah, me neither, although for a slightly different reason: I am not
sure why debug assertions and/or EB cannot be used for bitmap like
elsewhere, plus why having a custom config option is needed just for
bitmaps. See e.g.

  https://lore.kernel.org/rust-for-linux/CANiq72=tKVD13GD2Bzmt_LnC4SiOX1nkHQPcz2BS=P=b23e0Yw@mail.gmail.com/

I think consistency is important to help maintenance and to reduce
mental overhead for both contributors and maintainers.

Cheers,
Miguel
