In fact, the Ubuntu package renames it to "translate-bin". But that's awkward
to me: what's the difference between "translate" and "translate-bin"? One
should have to read both manpages to understand. But if we have, for example,
"translate-de-en" and "translate", the differences are clear. However, I don't
believe I'll ever use translate-bin.
Looking at the package information of translate, it already depends on a
"trans-de-en", which is clearer to me. (trans-de-en is the dictionary,
translate is the tool using it)

Agreed on that; educating upstream is sometimes difficult though (i.e. I
haven't contacted upstream yet -- I'd like to see if the thing is solvable
inside Debian)

As already stated, I'll do that only if really necessary / if the clash is
unsolvable. Please read further in the next paragraph.

I think not.
(from libtranslate-bin)
$ translate -h
Synopsis:
translate {-? | -v | --list-services}
translate [-s SERVICES] [-f LANG] [-t LANG] -l
translate [-s SERVICES] [-f LANG] [-t LANG] {HTTP_URL | HTTPS_URL}
translate [-s SERVICES] [-f LANG] [-t LANG] [--max-threads=N]
[--max-retries=N] [FILE]
...
-l, --list-pairs List the available language pairs
$ translate -l | wc -l
948
$
(from translate)
$ translate -h
...
USAGE:
translate [-niwvh] [-l languages] [words to translate]
...
$
where currently -l look for files in /usr/share/trans/. And there's just a
package providing files in the whole Debian distribution: trans-de-en:
$ apt-file search /usr/share/trans/
trans-de-en: usr/share/trans/de-en
$
I believe I can claim the use of the generic name "translate".
Using alternatives would be the best solution to me, since they provide
"more-or-less" the same functionality. Yet, translate covers only de-en, while
libtranslate-bin covers more pairs.
(and the main difference is that translate uses a local dictionary, while
libtranslate-bin needs an Internet connection to lookup translations)

True.
I won't post an RFS before solving this situation.
Kindly,
