Hey, good to learn about the SPDX project,
it is great that people care about these things.

As a first (maybe incorrect) impression: One thing that
gives me pause is that its documents come with a, for lack
of a better word, corporate "All other rights expressly
reserved" blurb. 

Also, even though the list of licenses they have collected is
long, I can't spot (and let me know if otherwise)
any newer ethical licenses - the ones one
can find by following links on writing.kemitchell.com

For instance, one could imagine somebody publishing
their capsule under a "free but no surveillance, no deduction
of personal information" license, and if there is a
gatekeeper who approves an "acceptable" license, then
this might be harder. Maybe if there is an open
process on how license names can be added to the
curated list (does anybody claim to own the database ?), 
this concern would be reduced...

Then there is the (quite) unusual matter of the gemini
syntax - how to accommodate the "SPDX-License-Identifier" 
token in gemini files. The gemini markup doesn't 
have a "label: value" format, and no comments - its
markup are things like "*" or "##' and maybe even
informally "--". Noting that this lack of extensibility is 
deemed a feature, not a bug... and correctly so in my
view.
