I just checked. This appears to be the way it always was:
-- atlas packages can transparently replace the normal blas
-- we usually default to the blas
-- if you install atlas, it gets found.
Ldd on R before I re-installed libatlas3gf-base:

and once you install it we have atlas:

Dito for 'ldd /usr/lib/R/lib/libRlapack.so'
So all that is different right now is that I am not doing the old Depends:
trick of defaulting to libblas with an alternate of libatlas. Given how
users need to install libatlas (either base or hardware-specific ones)
manually anyway, I see no real issue.

Oh, darn. Now I see -- you were talking about the -dev, not r-base-core.
But even that should be covered via libatlas-base-dev proving libblas-dev.
What am I missing here?
But in the meantime, lemme get the alternates back in.
