If mandree@ and allanjude@ (and you) are fine with it, we can use just the SPDX-License-Identifier and omit the full text of the license.

My take is we can replace the license by a reference if and only if we ship a local copy of the license "nearby" on the same media that's available offline, so that we don't depend on spdx.org or network connectivity.

If we don't have an offline copy near the script, I'd prefer and strongly recommend to just normalize the text and add the SPDX ID.

I'm perfectly fine with leaving this as is.
