If you don't use it, I do and it is one important function to my work,
I use it few times in few files related to variables interpolation in
templates and dynamic code fetching and re-use. And I have not ever
considered it `esoteric'.

grep --color=auto -nH -e dlet *.el
rcd-cf.el:6870:  (dlet ((wrs-text text))
rcd-cf.el:6889:  (dlet ((wrs::page (rcd-db-table-id-hash "pages" page-id cf-db))
rcd-cf.el:6919:    (dlet ((wrs::text (rcd-template-eval (gethash 
"pages_content" wrs::page "") '("⟦" "⟧") wrs::variables))
rcd-cf.el:6922:      (dlet ((wrs::template (gethash "templates_content" 
wrs::template))
rcd-utilities.el:1480:  (dlet ((wrs-processor "asciidoctor"))

For me it is not natural. `dlet' is supposed to bind variables
dynamically and with this change it doesn't. Basically the function is
ruined how I see it.

Your proposal is not logical and that you just changed it without
deeper analysis is very suprising.
