You sort of prove my point here, as you actually have your own
autoloader, which in case you are PSR compliant, you would not need,
you can still use your bootstrap but no longer implement the class.
Also bootstrapping is not a solution for smaller libraries that
include one or 2 classes, having to code an autoloader for everything
is redundant. And frankly having to make sure you do requires to get
the loaders is something i would rather get rid of. The day i can code
a whole application without a single require in it will be a blast.

This depends on the size of your library, bootstrapping might not be a
requirement, and from what i see around its actually used very little.
Anything needed is attached to your application or is done in the
construct methods.

Libraries can be more the collections of classes, or they can be just
collection of classes. Either way my comment was directed to both
cases.

Bootstrapping and autoloading are two parts of a process, having one
done better does not exclude having the other in your library.

So a see bootstrapping as a form of configuration and preparation,
autoloading is merely a step that may or may not be in this.
