Hi Alexios,
In light of further comments on this - would a happy medium perhaps be
to change that operators may be all uppercase or all lowercase?

for a conversation that started in 2015 and was finally resolved in
2020 with consensus on the current state.
If I remember correctly, since it was only a matter of personal
preferences[*], we decided to go with the easiest way and have a
single way of expressing an operator, in uppercase ASCII characters.
Noone was keen to start seeing things like “curl aNd Caldera oR MIT”.

I know it’s just a typo, but the identifiers /are/ the operands. It’s
the operations you’re discussing.

Does the operand case affect tooling? A quick Bing Chat tells me that
most languages have case sensitive Boolean values. Isn't our goal to
enable automation? I must confess that I have the opposite opinion,
that the upper case Booleans are easier to read and pick out, but I am
accustomed to writing Boolean statements.

Well, that's why I sent it to spdx@ and not the other lists.

Yes, I assume so. It doesn't make sense to me that the identifiers are
case-insensitive but the operands are case-sensitive. Admittedly, a
generous reading implies that the important aspect is that the
statement uses consistent case, but I know people have generally
interpreted it differently.
