`DD' *is* mentioned:
Other settings
Reg. Definition Effective Default
────────────────────────────────────────────────────────────────
DD Display, table, eqn, pic spacing next para. 0.5v
MINGW Minimum width between columns next page 2n
────────────────────────────────────────────────────────────────
A search for `DD' in the man page should quickly reveal its
existence :-)

The `terseness' is historically caused by the fact that macros were
always interpreted and never interned, and with a slow processor there
was a noticeable difference 30 years ago.
Compare this to the mdoc macros, which I've completely modernized some
years ago (together with Ruslan) to use long macro and variable names:
The macro file `doc.tmac' in the source code bundle has a size of more
than 150kByte; during installation, about 80kByte of comments and code
gets stripped off.
I've never found time to do something similar with with `s.tmac',
unfortunately.
