OK. I'll contact this guy in few weeks.

In that case, could it be treated differently?

IMO, `width=` should be the default completion and, in the rare cases
when the `=` is not wanted, it is easy to erase it.

Indeed, same issue. But what could be nice for `C-c C-m' would be to
type for us in the buffer (not the minibuffer) this damned backslash and
then, as soon as characters are typed, to provide a completion (à la
company).

Would be /very/ nice! :)

Sorry, the link above isn't accurate enough. What I wanted to point out
is not tables, but the screenshot about floating figures in section
``2.10.1 Inserting a picture using a "wizard"'',. By contrast, what is
provided in the minibuffer by `C-c C-e fig TAB` is much less rich.

Indeed, I always forget that the file has to be reload in order such
macros are taken into account (no such a pain in TXS).
What is missing compared to TXS is the placeholders: such placeholders
are:
- highlighted: boxed, the selected one having a colored background,
- quite explicit in case of existing completion file and, in case of
user macros such as the previous one, not so few explicit, here
\congru[opt. arg1]{arg2}
- easy to reach: there are shortcuts to jump between them.

Well:
- with AUCTeX, even after the file being reload, no completion for
`MyVerbatim` and the 1st RET inserts only the environment with the
cursor inside: no "Optional", etc.
- with TXS, `\be + TAB` is completed into `\begin{` and, then, we have
completion for all the known environments, including `MyVerbatim`
(but nothing more).
Best.
