I'm not expecting this number to rise, since it's mostly for experts that
prefer no abstraction whatsoever.

My issues is that I have no idea what "thin PSGI layer" means.

Dancer provides a thin layer above PSGI and abstraction for some of the work
a user would have to do manually (sessions, templating, finding out what
type of HTTP method it is, setting the content type, etc.). You (or rather,
Dancer, if that's what you're using) provide PSGI with an app handler
subroutine. For example:

  sub app {
      my $env = shift;
      return [
          [ 'Content-Type' => 'text/plain' ],
          [ "Hello World" ], # or IO::Handle-like object


How many people would do that? Very few.
