I've settled for this, taking inspiration from their project's page:

-     "@code{toml} is a library for Tom's Obvious, Minimal Language (TOML).")
+     "@code{toml} is a library for parsing and creating Tom's Obvious, Minimal
+Language (TOML) configuration files.")

Removed.

It now reads as:

-    (description "Defines the @code{dflet} macro to provide the historic
-behavior of @code{flet}, as well as @code{declare-function} stub for older
-Emacs.")
+    (description "address@hidden defines the @code{dflet} macro to
+provide the historic behavior of @code{flet}, as well as
address@hidden stub for older Emacs.")

It now reads as:

-and configures a number of other packages written in Emacs Lisp as well
-as Python.")
+and configures a number of other packages written in Emacs Lisp as well as
+Python, together offering features such as navigation, documentation,

I'm resending the modified full series of patches as v3, for ease of
use.

Thank you for reviewing!
