Termux has taken the approach of targeting an older version of Android
without these restrictions, meaning that it will no longer install on
some soon-to-be future version of Android; Android 14 will no longer
allow installing applications targeting Android 5.1 or later, and they
plan to ``progressively ramp up'' the target version requirement.

If they are free software, I don't see a problem with listing them in
the manual.
