Hmm yeah, it is irritating. The statement is at
https://spdx.org/licenses/ but only by virtue of two tables, the second
of which is the list of deprecated identifiers.
I'll put a paragraph about this in the commit message.

We have problematic uses of GPL in tree, where we don't for LGPL.
I'm considering a gitlab pass which will reject patches with use an
identifier not in the permitted list, and reject in introduction of new
uses of the deprecated ones. For this, the deprecated-but-tolerated
tags need calling out in some machine-readable way, but I don't think
it's helpful to express the tolerating of a tag we don't have any
violations of.
