I agree with both paragraphs above.

Me too. I didn't even know such a feature existed in MySQL/MariaDB. In
some tools where I come across auto-abbreviations I've disliked it. It
is difficult from documentation point-of-view to read and understand
if two commands do the same thing or not.

If people are too lazy to write long commands, then autocompletion is
a much better solution. I like very much how git does this: it has
both autocompletion and context-aware help if you run a command that
was wrong and maybe misspelled.
