The discussion on this issue has already begun in #878121 (which I'm
CC'ing).

Basically, as already said by Milan, I don't think we're going to bump
from 32- to 64-bit indexing. We're rather making them coexist, using a
different SONAME for 64-bit indexing, ideally by remaining as close as
possible to what other distributions have done (at least Fedora). That
probably also means introducing a new alternative for the 64-bit
version of BLAS and LAPACK, since one could also compile the reference
BLAS, ATLAS and LAPACK using 64-bit indexing.

I don't think I will have the time to do this for buster. But if you
want it quickly, and are willing to write patches, I will review them
and hopefully have them uploaded before the buster freeze.

Best,
