That is exactly my point; the whole rst stuff detracts from normal text.
It makes both reading and writing harder than it needs to be.

(google) Dictionary says:

"a punctuation mark (:) used to precede a list of items, a quotation, or
an expansion or explanation."

An enumeration (list) is just one of many possible uses of the colon.

I think typically there will be an 'empty' line between the colon ending
and the 'example/explanation'. This seems true for a number of comments
I found in drm using the '::' nonsense.

Simple regexes don't do multi-line patterns, but maybe the kerneldoc
thing can parse it differently.
