this is an unfortunate tradeoff. I'll gladly opt for improved runtime
performance vs improved build and deployment performance.
is it not possible, if not reasonable, to have both by adding a new class
that couples to the unshaded class in tandem to the current proposed class that
couples to the shaded? this seems like a reasonable tax on the choice to use a
shaded library and coupling to its internals.

> The hadoop-aws library has a dependency on
> 'com.amazonaws':aws-java-sdk-bundle' which in turn is a fat jar of all AWS
> SDK libraries and shaded dependencies.
>
> This dependency is 181MB.
>
> Some applications using the S3AFilesystem may be sensitive to having a large
> footprint. For example, building an application using Parquet and bundled
> with Docker.
>
> Typically, in prior Hadoop versions, the bundle was replaced by the specific
> AWS SDK dependencies, dropping the overall footprint.
>
> In 3.3 (and maybe prior versions) this strategy does not work because of the
> following exception:
