When I was searching for a solution to my problem (which I now consider
solved) I think I ran into a solution without the rename command… I think
they used mv instead, but I can't find it.

Is there a reason not to use rename (such as it might be slow or something,
maybe even incompatibility with non-Debian based systems)? I realise that I
need regular expressions to achieve the name change, which makes rename the
convenient choice, but there should be other ways, shouldn't it?

Unfortunately I never bookmarked the site where I found it (or THINK I found
it…).
