If we're going to introduce any kind of (semi-)automatic conversion of existing license tags, I think it'd be good to make "convert «and» and «or» to upper-case" part of the process. A.FI. [0] https://spdx.github.io/spdx-spec/v2.3/SPDX-license-expressions/#d2-case-sensitivity
*nod*
BTW based of the feedback of all of you and because it is very common error in writing SPDX formula in SPDXv3 it will likely be allowed to use "and", "or".
