Gladly. I believe this was simply cargo-culted from existing syntax
files. Should I also remove the
if version < 600
syntax clear
…
at the top of the file, since the apparent reason for HiLink is
backwards compatibility?

The Clojure language, being a Lisp, accepts many non-word characters in
its identifiers¹, so the purpose of augmenting 'iskeyword' is not just
for the benefit of the `syntax keyword` definitions.
The existing suite of Vim plugins that are designed to work with these
runtime files actually assume these additions to 'iskeyword' in order to
find word boundaries, so removing this would cause breakage, and then
plugin authors would simply augment 'iskeyword' themselves.
However, I can see now that setting 'iskeyword' in the syntax file
instead of the ftplugin is problematic because the setting becomes local
to the buffer and not to the filetype, which will cause confusion if a
user changes filetypes for a buffer.
Do you think it is an acceptable compromise if I change the `syntax
keyword` definitions to `syntax match` and move the 'iskeyword' setting
to the ftplugin?
Thank you for your attention.

¹ In Clojure, word boundaries are defined by whitespace, brackets, and
metacharacters for the Lisp reader.
For example, these functions and variables are in the standard lib:
*command-line-args*
list*
->
cond->>
zero?
set!
These non-word characters, along with a few others, are very widely
used as identifiers in the Clojure community
