I try quick start of mezzio.
When I install default, the choice is no template engine[n].
Which template engine do you want to use?  Plates (supported by laminas)  Twig (supported by laminas)  laminas-view installs laminas-servicemanager (supported by laminas) [n] None of the above <<< here Make your selection or type a composer package name and version (n):
Tracing the tutorial and access localhost:8080, I met a rendering error.
When I choice laminas-view, localhost:8080 successfully show the demonstration page.
And when I chose , I had to install a twig-renderer and must create template directives additionally .
I thins this behavior will surprise beginners and It leads to giving up on the choice of mezzio.
So please consider changing the default value, if you can.
