A practical difference in practice?

See `query-replace-regexp'.  Why do you think it
has argument DELIMITED?

Same question for `replace-regexp', `replace-search'
(with arg REGEXP-FLAG), `query-replace-regexp-eval',
`perform-replace', and `tags-query-replace'.

All of those allow a "from" arg that can be a regexp,
and they all accept a DELIMITED arg as well.
