The SBI 0.1 specification is obsolete. The current version is 0.3.
Hence we should not rely by default on SBI 0.1 being implemented.
It’s what BBL implements, and some people are still using it,
especially given early hardware shipped before OpenSBI grew in
popularity.

Do you mean BBL is not developed anymore?
Some people may still be using a 0.1 SBI. But that minority stuck on an
outdated software stack does not justify defaulting to deprecated
settings in future Linux releases.
